Abdullah bin Hisham reported,

He had met the Prophet ﷺ. His mother Zaynab bint Humayd took him to the Messenger of Allah ﷺ and said, "Messenger of Allah, accept his pledge of allegiance."The Prophet replied, "He is young." He then wiped his head and prayed for him.He used to sacrifice a single sheep on behalf of his entire household.

عن عبد الله بن هشام

- وكان قد أدرك النبي ﷺ- وذهبت به أمه زينب بنت حميد إلى رسول الله ﷺ فقالت: يا رسول الله بايعه، فقال النبي: هو صغير فمسح رأسه، ودعا له، وكان يضحي بالشاة الواحدة عن جميع أهله.
