Allah loved Sa`id and destined for him to grow up with a father who embraced the religion of Abraham, unified Allah, and disapproved Quraysh who were worshipping idols and slaughtering for other than Allah. Thus, Sa`id grow up with a heart ready for faith, and as soon as he heard about the call of Muhammad (peace be upon him), he hastened to it declaring his Islam while his age did not exceed twenty.

He was the brave boy, Sa`id ibn Zayd, who was born in Makkah in 22 AH.

He was known by his clear heart, soft temper, generousity, and modesty.
