Regarding tribalism
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الرَّحِيمِ، حَدَّثَنَا الْحُسَيْنُ بْنُ مُحَمَّدٍ، حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ، عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ، عَنْ دَاوُدَ بْنِ حُصَيْنٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عُقْبَةَ، عَنْ أَبِي عُقْبَةَ، - وَكَانَ مَوْلًى مِنْ أَهْلِ فَارِسَ - قَالَ شَهِدْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم أُحُدًا فَضَرَبْتُ رَجُلاً مِنَ الْمُشْرِكِينَ فَقُلْتُ خُذْهَا مِنِّي وَأَنَا الْغُلاَمُ الْفَارِسِيُّ فَالْتَفَتَ إِلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ " فَهَلاَّ قُلْتَ خُذْهَا مِنِّي وَأَنَا الْغُلاَمُ الأَنْصَارِيُّ " .
Narrated AbuUqbah: AbdurRahman ibn AbuUqbah quoted his father AbuUqbah who was a client from the people of Persia as saying: I was present at Uhud along with the Messenger of Allah (ﷺ), and on smiting one of the polytheists I said: Take this from me who is the young Persian. The Messenger of Allah (ﷺ) then turned to me and said: Why did you not say: Take this from me who is the young Ansari?
