The Secret of Longevity of Imam al-Mahdi

Author: Ayatullah al-Uzma Nasir Makarim Shirazi
Introducing the Criticism: We said that others criticize the belief of Shiites about Mahdi from the past that: If he is the son of Imam Hassan Askari and was born in the year 255 after Hijrah from his mother Narjis and is still alive then he is more than thousand years old now, while:
Neither our daily observations show us people with this old age!
Nor today’s science accepts that!
Nor it has historical example!

Study and Research:
We agree the criticizers in this matter that normal and ordinary ages which we usually see are not more than one-hundred years, and rarely reaches one-hundred and twenty years, and in out time, people who have reached one-hundred and fifty or sixty are considered as exceptions in the world.1
But it is not possible to suffice to these matters for a scientific discussion and research about the matter of the longevity and the following matter should be considered and we see that:
Does normal life have a constant limit? What does today’s physiology say about that?
Is there any way of increasing the lifetime?
Were there exceptional people who were different with normal humans in physical, spiritual, body parts, different senses and other general characteristics?
Does history really remember people with ages older than what we can see today?
And above all, it should be considered that who are these criticizers and what is their understanding from different religious issues?
Does Normal Life have a Constant Limit?
A small batter has limited lifetime; for example it works for 24 hours continuously; then its power ends.
For instance, a light bulb works for one thousand hours and then it dies.
Maybe an automobile works for 20 years.
Also, other human produces has approximate specific lifetime and average limit; albeit, if user uses them in good conditions then they work more and if they are used in bad conditions then they work less than the specified amount.
We have also different kinds of lifetime in nature; there are particle inside atoms, which live for only one-thousandth of a second and sometimes “one-hundred millionth” of a second, but in change the age of the earth is estimated to five thousand million years!
Now we should see that whether the lifetime of living creatures in nature is like the lifetime of our industrial products or not. For example, human lives about 80 years; a dove lives about 5 years; an insect about some months; a plain tree lives about 150 years and a flower shrub about 6 months.
In the past, a group of scientist believed in a system of normal lifetime in living creatures. For example: Pavlov believed that normal lifetime of human is 100 years.
Metchnikoff believed that normal lifetime of human is 150 to 160 years.
Kaufland, German physician, believed that normal lifetime of human is 200 years.
PflĂĽger, famous physiologist, believed that normal lifetime of human is 600 years.
And finally Bacon, English philosopher and scientist increased the number and said it is about 1000 years.
But this belief has been denied by today’s physiologists and the issue of constant limit of normal lifetime of human is invalidated.
According to Professor Smith, Columbia University: “As the sound barrier broke and moving equipments appeared with ultrasonic speed, some day the barrier of human lifetime will break and it goes beyond whatever we saw until now!”
The living evidence which is possible to introduce for proving this belief is the experiments that a group of scientists have performed on different plants or animals in laboratories and they was successful in increasing the lifetime of a living creature in conditions of laboratory up to “twelve times” more.
For example, an experiment which is performed on a plant with the lifetime of only two weeks shows that it is possible to keep it up to six months.
If assumable, such increment is possible on human lifetime then there will be humans with more than hundred years of age.
Another experiment has been performed on a fruit fly, which has a very short lifetime, and they were successful in increasing its lifetime up to “nine-hundred times”!
If assumable, this amazing and extraordinary increment becomes practical on human lifetime then a person lives more than seventy thousand years!
Albeit, most of us neither wish for such tiresome age nor accept it even for free, until the poet says: I am tried of these two days of life, O Khizr - What do you do who live forever And if assumable we accept that, the earth is not ready for accepting this much of living humans!

But our goal is studying the issue of longevity scientifically
We know that today, many biologists have seriously studied the issue of increasing human lifetime; if such thing was impossible then these researches seemed to be useless.
Nutritionists believe that lifetime is closely related with the way of eating and environmental conditions; they have studied the lifetime of queen bee, which lives several times more than normal bees, and have understood that this matter is the result of royal jelly which is produced by worker bees especially for the queen that is different with normal honey; and a group of scientists thought that it is possible to increase human lifetime for several times with large amounts of this jelly.
Psychologists say that human lifetime is strongly dependant on his/her thinking way and beliefs and human lifetime increases by having series of constructive and calming spiritualities and beliefs.
A group of physician believes that: Oldness is a kind of illness which appears because of atherosclerosis or “Metabolism Disorder”; and if we can overcome these factors by correct eating and effective medicine then we can defeat the oldness and we will have a long life.
All these discussions clearly proves this issue that the legend of “constant normal lifetime” is nothing more than a false legend; and it is not possible to consider a specific limit for the lifetime of living creatures.
Especially, by opening the way of space to humans and beginning of space travels, the issue of lifetime was considered more seriously; because it has become certain that our short lifetimes our not proper for taking long astronomical journeys. Sometimes, several thousand years of age is needed for making a small step in this expanded universe with current spaceships and tens of thousands of years is needed for farther destinations; therefore, some scientists have thought about another way of increasing the lifetime and that is using freezing system.
Maybe, this matter was discovered for the first time by observing some of living creatures who had kept their normal life while being frozen; for example, some while ago a frozen fish was found inside polar ices that the condition of ice layers showed that the fish is for five-thousand years ago!
At first they thought that the fish is dead, but after putting it in warm water they surprisingly saw that it began moving; it is recognized that it was alive during these five-thousand years but with a weak flame of life!
At this point, they thought if it would be possible to use this method for humans and for example, if it is possible to freeze a space traveler in his/her cabin and an automatic system gradually brings his/her body to normal conditions after hundreds or thousands of years then the problem of lifetime in space travels would be solved.
Now, some of physicians have thought that they use this system for the patients whom their treatment method has not been found yet, and for example, propose to those who have cancer, to go to deep sleep - or beyond sleep - by freezing method, and for example, return to normal conditions after two centuries that the treatment method of these illnesses is naturally found and treat them.
All these discussion, plans and proposals show that according to today’s knowledge, there is no constant limit for the lifetime of humans and other living creatures and its amount can be changed.
1. Some while ago I visited an old man who was not able of performing fasting in the holy month of Ramadan and was asking about the issue of atonement of fasting; I asked about his age and he answered 29 year old. And because he saw that I was surprised, he added that he doesn’t count the hundred and I say after one hundred years which means I am 129 years old!

Existence of Exceptional People
If we ignore the previous discussion and accept that humankind has constant limit of lifetime according to his primary nature; but, it is not possible to generalize this matter to everyone, because always there are exceptions among living creature which are not compatible with standards and criterions which we saw in natural and experimental sciences; and sometimes, science is incapable of interpreting their conditions.
Some people have been seen among humans who had extraordinary and completely exceptional senses or powers.
Some members can be seen among a specific genus of trees or animals, which apparently have specific growth or seemingly limited lifetime, that breaks all regulations and standards of their genus and appear in an extraordinary form; for instance:
1) Travelers, who have visited Scotland, talk about an amazing tree with 90 feet diameter in trunk and estimated five thousand years of age!
2) A tree has been seen in California, which are one hundred meters tall! And its lower diameter is about 10 meter and its age is estimated up to sic hundred years.
3) There is a tree from the genus dracaena or as it is called “dragon tree” among the trees which grow in Canary Islands, that has interested scientists; it is said about this tree that no change has been seen in its grow from the time of discovering the island (which is about five-hundred years ago)! But its seems to have a long life that through this time effects of time have not appears on its feature; therefore, some people think that perhaps, this tree was available before the creation of Adam!
4) There are trees in tropical regions, which live forever! It means that they are continuously growing roots and shoots and never die.
5) Some snails have been seen which are thousands years old; and biologists have discovered some fished which are about three million years old.
6) We can see some people with wonderful talents who are not believable even for those who see them with their own eyes. Who didn’t read the news about the young person who bent metal objects like fork and spoon with the extraordinary power of his eyes without even a small touch of his hands!
He performed this wonderful job before the eyes of reporters and even on TV in England that even incredulous British people accepted that there was no special trick and it is considered a special and exceptional condition.
Maybe, all people have read about the young Iranian who eats light bulb and glass like candies, while ordinary people may be taken to operation room if they accidentally eat a bit of glass with their food!
I read the story of a person in newspaper who subdued wild animals with his extraordinary power and approach them easily.
It is written about the conditions of philosopher and famous physician “Avicenna” that: When I went to school, I memorized anything which students read for the master; in the age of ten, I have knowledge of sciences that people were amazed of me in Bukhara; in the age of 12 I became a jurist! And issued fatwas in Bukhara; I wrote the book \"The Canon of Medicine\" in medicine at the age of 16 (the same book which was being taught in European universities for some centuries); amazing stories have been quoted about his different senses including sight or hearing and like them which cannot be told in this brief chapter.1
These are all exceptional people with characteristics that scientists of natural science are incapable of explaining them and their conditions are not compatible with criterions and standards of human characteristics which are available; but this in harmony never prevent us to accept them; and accept a general law under its light that what we have seen in “plants”, “creatures of deserts and seas” and “humans” is not an eternal and comprehensive law; but it is completely possible that some members are found among them with special and extraordinary characteristics, whether about the age or about spiritual and physical powers and abilities; and their exceptional condition will never be the reason for acceptance of these phenomena to be unscientific; but we should accept that the boundaries of all the laws and criterions which sciences give us are restricted to ordinary members and exceptional members are beyond the boundaries of these criterions and laws.

Who Made this Criticism?
If materialists, who see everything from natural laws’ point of view, make the criticism about the lifetime of Mahdi (as) then the answer is what has been said in previous discussions; but, if monotheists of the world like the followers of Christ (as) and Moses (as) or Sunni brothers make this criticism then we have other expressions for them adding to what we have said before, including:
1) They consider unlimited power for God and several extraordinary characteristics and miracles for his messengers; in other words, they consider God as the ruler of natural laws not being ruled by them; is treating incurable illnesses compatible with medical science, or are bringing back the dead to life by Christ or other wonderful miracles of Moses(as) by rod (a worthless peace of wood) and leprous hand and passing the Nile with that extraordinary event matters which are compatible with natural criterions and standards?
Undoubtedly, all the followers of religions say that the effects of natural laws and means are all by the order of God for interpretation of these phenomena, and anything he wills for something else then another thing happens and his will is beyond natural causes. If from the beginning dead people returned to life again or innate blind person gained his sight after a while or average limit of lifetime of an ordinary human was one-thousand years then was anyone surprised from these matters and did anyone consider them against the law of wisdom? … Certainly not!
Therefore, breaking these laws is not breaking a rational and logical order; but it is breaking an ordinary condition and way to which we have been accustomed by observing ordinary people and things.
2) Today’s Christians mostly believe that the enemies of Christ(as) crucified, killed and buried him; and after some days he rose from the dead and went to heavens and is still alive.
Although, Muslims don’t accept the crucifixion and murder of Jesus - according to Qur’an; but they believe that he is still alive; and this is the expression which all-Islamic scholars, except a few, have accepted.
If this exception is not against the wisdom, and it is possible for a human to become alive again after the death and burial and lives about two thousand years, then how is it possible to consider more simple cases impossible when it is only talked about a long life a little more than one thousand years!
3) There is no Muslim who denies the long life of Noah, because it is mentioned explicitly in Qur’an that only the time of his calling to monotheism was nine hundred and fifty years
Surah Ankabut 29: 14
Also, we have heard about Khizr and his loge life.
It is amazing that a group of people has accepted all these matters, but when they face the belief of Shiites about the age of “Mahdi”, they have surprising faces and move their head as the sign of denial and have smiles, which means that how these kinds of irrational and illogical beliefs can have followers?!...
This is a clear example of “being in one roof and having two climates” (referring to a Persian proverb)!
But, as we said before, the matter of longevity is completely understandable according to the logic of natural sciences regardless of the beliefs of monotheists about the power of God and the issue of miracles; the only problem in the way is that we free ourselves from prejudices and special biases, and traditions and costumes to which we have been accustomed and only surrender ourselves to reason and logic and free discussion!
We are amazed when we read in newspapers about a 140-years-old Austrian man who hadn’t become ill through his lifetime, even once!
Or a man was completely young at the age of 167 in Colombia!
Or a man’s hair was black at the age of 253 in china!
Because it is against ordinary and normal people; but if the sources of this news are reliable but it is written in all newspapers as certain news then we will accept it.
But why we are amazed when we read in hadith: When al-Qa’im rises, he has the age of the old but the face of the young and he is also physically powerful.
Shi’a says: How don’t we laugh at those who accept the long life of Noah and Christ and write these amazing characteristics about Avicenna, or after watching a young person bending metals just by looking at them, or observing too old creatures and trees? But when it is talked about the long life of Mahdi (as), a group has objecting faces and say surprisingly that how is it possible for a man to have this age!
The issue of longevity is not the issue, which can be denied or criticized, in a fair and logical judgment.

The Philosophy of Long Occultation
We said that another question which is asked about the belief of Shiites about Mahdi (as) is the issue of his long occultation which is asked after accepting the matter of long life and that is: Why doesn’t Mahdi rise while corruption and oppression are available enough in the world?
Why doesn’t he move the world toward justice by his rise?
How long should we sit and watch the scenes of oppression and bloodshed of a bunch of criminals?
Why has his occultation lasted so long?
In fact, what is he waiting for?

And finally, what is the secret of this long occultation?
But it should be considered that although, this question is being asked from Shiites about the issue of occultation but it is recognized by a little notice that others also have a share of that; it means that, it points to other believers of the advent of a great universal peacemaker who should rise some day and fills the earth with justice in another form, however, the don’t accept the belief of Shi’a about longevity and occultation.
Because this question could be asked that why that great universal peacemaker is not born yet and if he is born then why doesn’t he rise and waters the thirsty world with justice? Therefore, it is a big mistake to only criticize Shi’a about this belief.
And in other words, there is no doubt that the issue of longevity (previous discussion) and the issue of the philosophy of existence of imam during the occultation (next discussion) are question which are pointed only to Shiites, but the matter of delay in his advent is the issue which all those who believe in the advent of that great universal peacemaker should think about that why the great advent doesn’t happen by readiness of the world? (Attention


Anyway, this question has a short answer and an explained one; its short answer is that solely the existence of a competent revolutionary leader is not enough for establishment of a multidimensional revolution and public readiness is also necessary; and unfortunately, the world is not ready for accepting such government yet and when it becomes ready, his rise is certain!
But the explanation is that: Firstly, it should be considered that - as we mentioned before - the plan of the rise of Mahdi uses natural tools and means, like the plan of the rise of all divine prophets, and it is never based upon miracles; miracles are exceptions and are not included in progress of reformist plans of divine leader, except in exceptional cases.
Accordingly, all prophets used modern weapons, teaching competent persons, necessary consultations, designing effective plans, studied military tactics and totally providing any kinds of material and spiritual facilities for reaching their goals; and didn’t wait for a miracle everyday to defeat the enemies or in order to encourage the friends for advancing more in the way of perfection.
Therefore, the plan of government of truth and justice in the world should be established by the use of necessary material and spiritual means, except in exceptional cases.
In other words, Mahdi (as) doesn’t bring new religion with him, but he executes divine plans, which are not executed. His prophecy is not only imparting, warning, teaching, training, advising and admonishing. His prophecy is executing all principles that end oppression, injustice and discrimination under the shadow of government of science and belief, and certainly execution of this plan is not possible without readiness and preparations.
Secondly, it is clear according to the above essential principle that hwy we say the existence of this readiness is not proved yet; because, at least, some kinds of readiness are needed for this matter:

Preparedness for Acceptance (Mental Preparedness)
The people of the world should understand the bitterness of this inharmonious conditions and injustices enough.
The people of the world should feel the incapability and incompleteness of human laws for execution of social justice.
The people of the world should understand this truth that only material principles and relations won’t solve problems of the world and available execution assurances and regulations made by humans, but problems become more congested every day and more complicated like an endless clew.
The people of the world should feel that current crises are the results of current systems; and finally, these systems are incapable of solving the crises.
The people of the world should feel that new principles and systems are needed, which depend on human values, faith, human affections and moralities, for reaching this great goal not only harsh, soulless, incomplete material principles.
The people of the world should reach the stage of growth that understand the advancement of technology doesn’t necessarily means the advancement of humanity and providing happiness for humans; but advanced technology can assure happiness only if it is installed under supervision of series of spiritual and human principles, otherwise - as we have seen many times - will cause catastrophe and destruction.
The people of the world should recognize that if industries become idols then current problems will become bigger and it increases the amount of destruction and harmful effects of wars; but they should become the tools under the control of competent humans.
Finally, the people of the world should become thirsty and until they are not thirsty they won’t search for water streams.
And in other words, until there is no demand in the people of the world, offering no kind of corrective plan will be useful and effective; that the law of “demand and offer” should be more considered in social issues as it is interested in financial issues.
This question is asked that what should cause this condition of thirst and demand.
We answer: a part of that should be made by the pass of time and it is not possible without that, but another part depends on teaching and training; it should become practical by intellectual resurrection which is made by faithful thinkers and responsible aware persons of society.
At least, they should give this knowledge and understanding with their human-maker programs to the people of the world that essential problems of the world won’t be solved by available principles, laws and methods. And anyhow, it also needs time.

Cultural and Industrial Evolution
Gathering all the people of the world, dethroning the tyrants in everywhere, expanding education at its maximum level in all stages, clearing this matter completely that difference of language, race, and geographical region and like that is not a reason for the people of the world not to live in a family like brothers and life in peace, justice and brotherhood, and providing a healthy and enough economy for all the humans needs cultural growth and advancement of human knowledge on the one hands, and evolution of industrial equipments on the other hand; equipments which can connect all parts of the world very fast, close and permanently, which it is not possible without the pass of time, either.
How is it possible for a government to control the entire world if connections are slow!
How is it possible to rule the world by the equipments, which need one or some years for sending a message to faraway parts of the world!
It is understood from a part of narratives, which picture the lifestyle of the people of the world at the time of Mahdi(as), - and we will discuss about it completely later, God willing - that the advancement of technology and industries, especially transmissions and communications, in that time is in the way that large continents of the world practically become as some neighbor cities; and even the East and the West will be considered as one home; the problem of the time and place will be completely solved.
Albeit, it is possible that some of these matters happen in that time in the form of an industrial revolution, but anyway, a scientific preparedness is needed as the background at the beginning of this age.

Training a Revolutionary Strike Force
Finally, a group of people, although in minority, is needed to form the core of the army of that great peacemaker.
Flowers should grow among this burning hell to be the beginning of a flower garden; saplings should be grown in this heath in order to promise the spring for the others.
Extraordinary aware, brave, compassionate, devoted persons should be trained for this act, although generations pass one after another for this purpose, until the main reservations appear and main members of the revolution are gathered, and it also need time.
But, who should take the responsibility of training these persons?
We should know that it is upon that great leader who executes such plan directly or indirectly (for explanation about this matter will be mentioned in the next discussion, god willing).
In Islamic narratives, one of the reasons of long occultation is said to be the issue of public examination and choosing the most competent one, which maybe points to this subject.
Explanation: Divine human examinations are not like the examination for measuring the abilities of the one who is being examined, but they are for training the talents and disclosing the abilities and separating the rows from each other.
And in other words, their goal is training, evolution or preparing; because unlimited knowledge of God about everything removes any kind of goal of measuring from the examinations.
Totally, this discussion cleared that why the occultation of Mahdi should be so long?

The Philosophy of Existence of Imam during the Occultation
Another question which is asked about the belief of Shi’a about Mahdi (as) and its characteristics is that: Imam (as) is leader anyway and existence of a leader can be useful if he has continues contact with his followers; how is it possible for an occult and unseen Imam to play the role of a leader?!
In other words, life of Imam (as) during the occultation is a personal life not a social life as a leader; in this case, we have the right to ask that what is the effect of this divine reservation for public and how can people take benefit from him?
He is like the pure stream of life that is in occultation and no one has access to him!
Moreover, essentially, is the meaning of occultation of Imam (as) becoming an invisible soul or unseen waves and like them?

Is it compatible with science?
Undoubtedly, this is an important question; but it is a mistake to assume that it has no answer; but let us first answer the last question, which has caused a complicated misunderstanding for a group of people and then clearing other questions.
We should explicitly say that the meaning of the occultation of Imam(as) - as we have said before - is not in the way that the existence of Imam(as) during the occultation is an invisible and dreamy existence that is more like an imaginative existence to an objective one.
But, about the life, he has an external objective life, but with a long life; he lives among the people and inside societies and lives in different places; and if there is an exception in his life is that he has a long life; that’s all.
He lives in human society unknown, and nobody has said anything else about his occultation; and what a difference between “unknown” and “invisible”!
