Abdullah bin Hisham (may Allah be pleased with him) said that his mother, Zaynab bint Humayd (may Allah be pleased with her), took him to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah (peace and blessings be upon him)! Take his pledge of allegiance." He (peace and blessings be upon him) said: "He is young." He (peace and blessings be upon him) passed his hand over his head and supplicated for him. And he would always offer one sacrifice on behalf of his entire household.
