Advancement of Islam in Madinah
The invitation of the Holy Prophet (SA) to Islam was widely extended in Madinah and it had embraced every home, association, district, and quarter. The people embraced Islam in groups and multitudes in such a way that the people in Makkah, Madinah, and all the tribes in the surrounding areas submitted to Islam. During the ten years of the Holy Prophet's (SA) stay in Madinah, absolute domination of Islam established in the entire Arabian Peninsula.
In these ten years, the Holy Prophet (SA) was preoccupied with carrying out his mission and never took rest.
He received wahy and taught the people the sublime teachings of Islam concerning education, ethics, and laws revealed to him by the Almighty Allah. The Holy Prophet (SA) gave people the necessary advice, answered their questions, discussed and debated with the opponents and scholars of various nations especially those of the Jews, and managed the affairs of the country, thus enabling the people to administer lives.
In spite of all these preoccupations, the Holy Prophet (SA) devoted a considerable part of his time for worshipping Allah. He observed Sawm on many days of the year, that is to say, he observed Sawm almost continuously during the three consecutive months of Rajab, Sha'ban, and Ramadan and also observed Sawm for about a month on different occasions during the year. Sometimes, the Holy Prophet (SA) observed the Sawmul Wisal (continuous fasting) which was one of his special characteristics, i.e., he did not take anything for several consecutive days and nights. He used to spend some of his time in the management of household affairs and necessities of life. Also, at times, he spent his time to earn his subsistence.
The Almighty Allah has briefly mentioned the events of these ten years in His words: "They desire to put out the light of Allah with their mouths, but Allah will perfect His light, though the unbelievers may be averse (61:8)"
Allah is the One who has sent His messenger with divine guidance and true religion to the people to make His religion dominant over all other religions and faiths, even if this is unpleasant for the polytheists.
As it is evident, this divine promise had been well realized during the lifetime of the Holy Prophet (SA) and after his passing away to the present day when more than one billion Muslims live all over the world.
He also states: "You are the best of the ummahs (peoples) raised up for (the benefit of) men; you enjoin what is right and forbid the wrong and believe in Allah ... (3:100)"
