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 ﷺ 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 .

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ حَدَّثَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، أَنَّ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ إِنَّ عُتْبَةَ بْنَ أَبِي وَقَّاصٍ عَهِدَ إِلَى أَخِيهِ سَعْدِ بْنِ أَبِي وَقَّاصٍ أَنْ يَقْبِضَ إِلَيْهِ ابْنَ وَلِيدَةِ زَمْعَةَ، قَالَ عُتْبَةُ إِنَّهُ ابْنِي. فَلَمَّا قَدِمَ رَسُولُ اللَّهِ ﷺ زَمَنَ الْفَتْحِ أَخَذَ سَعْدٌ ابْنَ وَلِيدَةِ زَمْعَةَ. فَأَقْبَلَ بِهِ إِلَى رَسُولِ اللَّهِ ﷺ وَأَقْبَلَ مَعَهُ بِعَبْدِ بْنِ زَمْعَةَ. فَقَالَ سَعْدٌ يَا رَسُولَ اللَّهِ هَذَا ابْنُ أَخِي عَهِدَ إِلَىَّ أَنَّهُ ابْنُهُ. فَقَالَ عَبْدُ بْنُ زَمْعَةَ يَا رَسُولَ اللَّهِ هَذَا أَخِي ابْنُ وَلِيدَةِ زَمْعَةَ، وُلِدَ عَلَى فِرَاشِهِ. فَنَظَرَ رَسُولُ اللَّهِ ﷺ إِلَى ابْنِ وَلِيدَةِ زَمْعَةَ، فَإِذَا هُوَ أَشْبَهُ النَّاسِ بِهِ، فَقَالَ رَسُولُ اللَّهِ ﷺ " هُوَ لَكَ يَا عَبْدُ بْنَ زَمْعَةَ ". مِنْ أَجْلِ أَنَّهُ وُلِدَ عَلَى فِرَاشِ أَبِيهِ، قَالَ رَسُولُ اللَّهِ ﷺ " احْتَجِبِي مِنْهُ يَا سَوْدَةُ بِنْتَ زَمْعَةَ ". مِمَّا رَأَى مِنْ شَبَهِهِ بِعُتْبَةَ. وَكَانَتْ سَوْدَةُ زَوْجَ النَّبِيِّ ﷺ.
