It is narrated from Abdullah bin Hisham (may Allah be pleased with him) that his mother Zainab bint Humayd took him to the service of the Prophet (peace and blessings of Allah be upon him) and said, "O Messenger of Allah! (peace and blessings of Allah be upon him) take his pledge of allegiance." The Prophet (peace and blessings of Allah be upon him) said, "He is still a child." Then the Prophet (peace and blessings of Allah be upon him) placed his hand on his head and prayed for him. He used to offer only one goat as sacrifice on behalf of his entire family.
