In the accounts of this period that have come down to us there is no mention of Ali. By this time Ali had come of age. He was well educated, highly intelligent, most enterprising and brave. It is difficult to believe that if the accounts make no mention of Ali, the inference is that he was idle and had nothing to do. When Abu Talib decided to espouse the cause of Muhammad (peace be on him), Ali most probably played an important part in prevailing upon Abu Talib to take the decision he did. We know that when the Holy Prophet migrated to Yathrib, he entrusted the responsibility for winding up the business in Makkah to Ali. In the accounts that have come down to us the Holy Prophet is shown as a good manager and businessman, but in the accounts of the post-prophethood period there is no account of any business activity on the part of the Prophet. The writers of the period apparently harbored the delusion that any business undertaking was repugnant to prophethood. An impression is tried to be created that in the post-prophethood period the Holy Prophet undertook no business and depended on the wealth of his followers, Abu Bakr, Othman and others. This is an erroneous presentation, for Islam is not a religion for the next world alone, it is a religion for this world as well. To abstain from business may be the Christian or the Buddhist concept of piety, but that is not the Islamic concept of prophethood. The Holy Prophet is the greatest man of all times and such a man perfect in every way cannot be without independent sources of income. It appears that when Ali came of age, the Holy Prophet entrusted the responsibility for running the business to Ali. It appears that during the period of the social boycott Ali continued to run the business of the holy Prophet (SAW). The boycott agreement merely restricted the sale or purchase by the Quraish; it did not and could not apply to business transactions elsewhere. It appears that Ali undertook business journeys during this period, and the necessary provisions procured from outside Makkah were duly supplied to the Banu Hashim in the glen.
