"Bear witness that I have given An-Nu'man such and such of my wealth as a gift." He said: "Have you given all your children a present like that which you have given to An-Nu'man?" (Using translation from Nasāʾī 3679)
انْطَلَقَ بِهِ أَبُوهُ يَحْمِلُهُ إِلَى النَّبِيِّ ﷺ فَقَالَ اشْهَدْ أَنِّي قَدْ نَحَلْتُ النُّعْمَانَ مِنْ مَالِي كَذَا وَكَذَا قَالَ «كُلَّ بَنِيكَ نَحَلْتَ مِثْلَ الَّذِي نَحَلْتَ النُّعْمَانَ؟»
My father took me to Messenger of Allah ﷺ and said: Messenger of Allah, bear witness that I have given such and such gift to Nu'man from my property, whereupon he (the Holy Prophet) said: Have you conferred upon all of your sons as you have conferred upon Nu'man? He said: No. Thereupon he (the Holy Prophet) said: Call someone else besides me as a witness. And he further said: Would it, please you that they (your children) should all behave virtuously towards you? He said: Yes. He (the Holy Prophet) said: Then don't do that (i e. don't give gift to one to the exclusion of others).
انْطَلَقَ بِي أَبِي يَحْمِلُنِي إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ اشْهَدْ أَنِّي قَدْ نَحَلْتُ النُّعْمَانَ كَذَا وَكَذَا مِنْ مَالِي فَقَالَ أَكُلَّ بَنِيكَ قَدْ نَحَلْتَ مِثْلَ مَا نَحَلْتَ النُّعْمَانَ قَالَ لاَ قَالَ فَأَشْهِدْ عَلَى هَذَا غَيْرِي ثُمَّ قَالَ أَيَسُرُّكَ أَنْ يَكُونُوا إِلَيْكَ فِي الْبِرِّ سَوَاءً قَالَ بَلَى قَالَ فَلاَ إِذًا

“Bear witness that I have given Nu'man such and such from my wealth.” He said: “Have you given all your children something like that which you have given to Nu'man?” He said: “No.” He said: “Then let someone other than me bear witness to that.” And he said: “Would you not like all your children to honor you equally?” He said: “Of course.” He said: “Then do not do this.”
