Background of Revelation
Ad-Durr-ul-Manthur reports from Ibn Jarir that a person embraced Islam and one of his friends rebuked him for having abandoned his forefather's religion. He responded that he fears Allah's chastisement. The friend told him to make a certain payment to him, and he will take upon himself his punishment of the Hereafter. Thus he [ the new Muslim ] will be spared from the chastisement, and consequently he made the payment to him. The friend demanded more payment. After a scuffle, he made the additional payment to him, and for the balance a document was drawn up with signatures of witnesses. That person, according to Ruh-ul-Ma’ ani, was Walid Ibn Mughirah who was inclined towards Islam. But his friend reproached him and took the responsibility of punishment upon his own shoulders.
