فَلَمَّا قَضَيْنَا عَلَيْهِ ٱلْمَوْتَ مَا دَلَّهُمْ عَلَىٰ مَوْتِهِۦٓ إِلَّا دَآبَّةُ ٱلْأَرْضِ تَأْكُلُ مِنسَأَتَهُۥ ۖ فَلَمَّا خَرَّ تَبَيَّنَتِ ٱلْجِنُّ أَن لَّوْ كَانُوا۟ يَعْلَمُونَ ٱلْغَيْبَ مَا لَبِثُوا۟ فِى ٱلْعَذَابِ ٱلْمُهِينِ

Chapter: To file a case for fulfilling the will of the deceased
Narrated Aisha:
Abu bin Zam`a and Sa`d bin Abi Waqqas carried the case of their claim of the (ownership) of the son of a slave-girl of Zam`a before the Prophet. Sa`d said, "O Allah's Messenger (ﷺ)! My brother, before his death, told me that when I would return (to Mecca), I should search for the son of the slave-girl of Zam`a and take him into my custody as he was his son." 'Abu bin Zam`a said, 'the is my brother and the son of the slave-girl of my father, and was born or my father's bed." The Prophet (ﷺ) noticed a resemblance between `Utba and the boy but he said, "O 'Abu bin Zam`a! You will get this boy, as the son goes to the owner of the bed. You, Sauda, screen yourself from the boy."
