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 (PBUH), and on smiting one of the polytheists I said: Take this from me who is the young Persian. The Messenger of Allah (PBUH) then turned to me and said: Why did you not say: Take this from me who is the young Ansari? Translation Not Available
