"My father took me to the Messenger of Allah to ask him to bear witness to a gift that he had given me. He said: 'Do you have any other children besides him?' He said: 'Yes.' He said: 'Treat them equally.'" (Using translation from Nasāʾī 3686)
سَمِعْتُ النُّعْمَانَ بْنَ بَشِيرٍ يَقُولُ انْطَلَقَ بِي أَبِي إِلَى رَسُولِ اللهِ ﷺ يَعْنِي يُشْهِدُهُ عَلَى عَطِيَّةٍ يُعْطِينِيهَا فَقَالَ هَلْ لَكَ وَلَدٌغَيْرُهُ؟ قَالَ نَعَمْ قَالَ فَسَوِّ بَيْنَهُمْ
