ذِكْرُ خَبَرٍ خَامِسٍ يُصَرِّحُ بِتَرْكِ اسْتِعْمَالِ الْإِيثَارِ لِلْمَرْءِ فِي النَّحْلِ بَيْنَ وَلَدِهِ

[Machine] My father referred to me in such and such a way, and the Messenger of Allah ﷺ came to testify. He said, "Did you give your children the same treatment as you gave [this person]?" He replied, "No." Then the Messenger of Allah ﷺ said, "Testify against him, for this is injustice." Then he said, "Do you like them to be treated equally in goodness?" He said, "Yes." He said, "So in that case, no."  

ابن حبّان:٥١٠٦ – أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ الْأَزْدِيُّ قَالَ حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ قَالَ أَخْبَرَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ قَالَ حَدَّثَنَا دَاوُدُ بْنُ أَبِي هِنْدٍ عَنِ الشَّعْبِيِّ عَنِ النُّعْمَانِ بْنِ بَشِيرٍ قَالَ

إِنَّ أَبِي نَحَلَنِي كَذَا وَكَذَا فَأَتَى بِي رَسُولَ اللَّهِ ﷺ لِيُشْهِدَهُ فَقَالَ «أَكُلَّ وَلَدِكَ أَعْطَيْتَ مِثْلَ مَا أَعْطَيْتَ؟ » فَقَالَ لَا فَقَالَ رَسُولُ اللَّهِ ﷺ «أَشْهِدْ عَلَى هَذَا غَيْرِي هَذَا جَوْرٌ» ثُمَّ قَالَ «أَتُحِبُّونَ أَنْ يَكُونُوا فِي الْبِرِّ سَوَاءً؟ » قَالَ نَعَمْ قَالَ «فَلَا إِذًا»

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
