The kunya Abu'l-Hakam

Hani' ibn Yazid related that when he came to the Prophet ﷺ with his people, the Prophet heard them using the kunya Abu'l-Hakam. The Prophet ﷺ called him and said, "Allah is the Judge (al-Hakam) and He has judgement. Why have you been given the kunya Abu'l-Hakam?" He said, "When my people disagree about something, they bring it to me and I judge between them so that both parties are content." "How excellent this!" the Prophet exclaimed. Then he asked, "Do you have any children?" Hani' replied, "I have Shurayh, 'Abdullah and Muslim, the Banu Hani'.' He asked, "Which of them is the oldest?" "Shurayh," he replied. He said, "You are Abu Shurayh," and he made supplication for him and his children.

حَدَّثَنَا أَحْمَدُ بْنُ يَعْقُوبَ، قَالَ: حَدَّثَنَا يَزِيدُ بْنُ الْمِقْدَامِ بْنِ شُرَيْحِ بْنِ هَانِئٍ الْحَارِثِيُّ، عَنْ أَبِيهِ الْمِقْدَامِ، عَنْ شُرَيْحِ بْنِ هَانِئٍ قَالَ: حَدَّثَنِي هَانِئُ بْنُ يَزِيدَ، أَنَّهُ لَمَّا وَفَدَ إِلَى النَّبِيِّ ﷺ مَعَ قَوْمِهِ، فَسَمِعَهُمُ النَّبِيُّ ﷺ وَهُمْ يُكَنُّونَهُ بِأَبِي الْحَكَمِ، فَدَعَاهُ النَّبِيُّ ﷺ فَقَالَ: إِنَّ اللَّهَ هُوَ الْحَكَمُ، وَإِلَيْهِ الْحُكْمُ، فَلِمَ تَكَنَّيْتَ بِأَبِي الْحَكَمِ؟ قَالَ: لاَ، وَلَكِنَّ قَوْمِي إِذَا اخْتَلَفُوا فِي شَيْءٍ أَتَوْنِي فَحَكَمْتُ بَيْنَهُمْ، فَرَضِيَ كِلاَ الْفَرِيقَيْنِ، قَالَ: مَا أَحْسَنَ هَذَا، ثُمَّ قَالَ: مَا لَكَ مِنَ الْوَلَدِ؟ قُلْتُ: لِي شُرَيْحٌ، وَعَبْدُ اللهِ، وَمُسْلِمٌ، بَنُو هَانِئٍ، قَالَ: فَمَنْ أَكْبَرُهُمْ؟ قُلْتُ: شُرَيْحٌ، قَالَ: فَأَنْتَ أَبُو شُرَيْحٍ، وَدَعَا لَهُ وَوَلَدِهِ.
