"My mother asked my father for a gift and he gave it to me. She said: 'I will not be contented until you ask the Messenger of Allah to bear witness.' So my father took me by the hand, as I was still a boy, and went to the Messenger of Allah. He said: 'O Messenger of Allah, the mother of this boy, the daughter of Rawahah, asked me for a gift, and she wanted me to ask you to bear witness to that.' He said: 'O Bashir, do you have any other child apart from this one?' He said: 'Yes.' He said: 'Have you given him gifts like that which you have given to this one?' He said: 'No.' He said: 'Then do not ask me to bear witness, for I will not bear witness to unfairness.'" (Using translation from Nasāʾī 3682)
سَأَلَتْ أُمِّي أَبِي بَعْضَ الْمَوْهِبَةِ لِي فَوَهَبَهَا لِي فَقَالَتْ لَا أَرْضَى حَتَّى تُشْهِدَ رَسُولَ اللهِ ﷺ قَالَ فَأَخَذَ أَبِي بِيَدِي وَأَنَا غُلَامٌ وَأَتَى رَسُولَ اللهِ ﷺ فَقَالَ يَا رَسُولَ اللهِ إِنَّ أُمَّ هَذَا ابْنَةَ رَوَاحَةَ زَاوَلَتْنِي عَلَى بَعْضِ الْمَوْهِبَةِ لَهُ وَإِنِّي قَدْ وَهَبْتُهَا لَهُ وَقَدْ أَعْجَبَهَا أَنْ أُشْهِدَكَ قَالَ يَا بَشِيرُ أَلَكَ ابْنٌ غَيْرُ هَذَا؟ قَالَ نَعَمْ قَالَ فَوَهَبْتَ لَهُ مِثْلَ الَّذِي وَهَبْتَ لِهَذَا؟ قَالَ لَا قَالَ فَلَا تُشْهِدْنِي إِذًا فَإِنِّي لَا أَشْهَدُ عَلَى جَوْرٍ
