Amin (Trustworthy): A Title of the Holy Prophet (S.A.W.)
Every historian has recorded that even prior to the declaration of his prophethood, the disbelievers of Quraish addressed the Holy Prophet (S.A.W.) by the title of ‘Amīn’.
The disbelievers trusted him to the extent that even though they did not heed his call and did not profess Islam, they deposited their valuables with him. The trust in the Prophet’s trustworthiness was not restricted to the Quraish tribe, but was shared by the people of other tribes and areas as well.
When these people came to Makkah during the Hajj season they used to put their belongings in the safe custody of the Holy Prophet (S.A.W.). This continued after the declaration of prophethood.
When the Prophet (S.A.W.) migrated to Madinah he gave all the things that were in his custody to Hazrat ‘Ali (A.S.) and said:
“Proclaim loudly, every morning and evening in Makkah that whoever had kept anything with Muhammad (S.A.W.) may collect it.”
