What was the reaction of the Prophet Muhammad (saw) when he saw the son of Zam`a's slave-girl?
 Narrated `Aisha:                     `Utba bin Abi Waqqas authorized his brother Sa`d 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, Sa`d took the son of the slave-girl 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's 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 .
