Volume 3, Book 46, Number 710:
Narrated ‘Aisha:
Utba bin Abi Waqqas authorized his brother Sad bin Abi Waqqas to take the son of the slave-girl
of Zam’a into his custody, telling him that the boy was his own (illegal) son. When Allah’s Apostle
went (to Mecca) at the time of the Conquest, Sad took the son of the slavegirl of Zam’a to Allah’s
Apostle and also brought ‘Abu bin Zam’a with him and said, “O Allah’s Apostle! This is the son of my
brother ‘Utba who authorized me to take him into my custody.” ‘Abu bin Zam’a said, “O Allah’s
Apostle! He is my brother, the son of Zam’a’ slave-girl and he was born on his bed.” Allah’s Apostle
looked at the son of the slave-girl of Zam’a and noticed much resemblance (to ‘Utba). Allah’s Apostle
said, “It is for you, O ‘Abu bin Zam’a as he was born on the bed of your father.” Allah’s Apostle then
told Sauda bint Zam’a to observe veil in the presence of the boy as he noticed the boy’s resemblance
to ‘Utba and Sauda was the wife of the Prophet .
