حَدَّثَنَا أَحْمَدُ بْنُ عَبْدِ اللَّهِ بْنِ يُونُسَ ، حَدَّثَنَا زُهَيْرٌ ، حَدَّثَنَا أَبُو الزُّبَيْرِ ، عَنْ جَابِرٍ ، قَالَ قَالَتِ امْرَأَةُ بَشِيرٍ انْحَلِ ابْنِي غُلاَمَكَ وَأَشْهِدْ لِي رَسُولَ اللَّهِ صلى الله عليه وسلم . فَأَتَى رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ إِنَّ ابْنَةَ فُلاَنٍ سَأَلَتْنِي أَنْ أَنْحَلَ ابْنَهَا غُلاَمِي وَقَالَتْ أَشْهِدْ لِي رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ " أَلَهُ إِخْوَةٌ " . قَالَ نَعَمْ . قَالَ " أَفَكُلَّهُمْ أَعْطَيْتَ مِثْلَ مَا أَعْطَيْتَهُ " . قَالَ لاَ . قَالَ " فَلَيْسَ يَصْلُحُ هَذَا . وَإِنِّي لاَ أَشْهَدُ إِلاَّ عَلَى حَقٍّ " .
Give to my son your slave as a gift, and make for me Allah's Messenger (ﷺ) a witness He came to Allah's Messenger (ﷺ) and said: The daughter of so and so (his wife Amra bint Rawaha) asked me to give my slave as a gift to her son, and call for me Allah's Messenger (ﷺ) as a witness. Thereupon he (the Holy Prophet) said: Has he (Nu'man) brothers? He (Bashir) said: Yes. He (further) said: Have you given to all others as you have given to him? He said: No. He said: Then it is not fair; and verily I cannot bear witness but only to what is just.
