Sahih al-Bukhari 3477
Narrated `Abdullah:
As if I saw the Prophet (ﷺ) talking about one of the prophets whose nation had beaten him and caused him 
to bleed, while he was cleaning the blood off his face and saying, "O Allah! Forgive my nation, for 
they have no knowledge."
حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، قَالَ حَدَّثَنِي شَقِيقٌ، قَالَ عَبْدُ اللَّهِ كَأَنِّي أَنْظُرُ إِلَى النَّبِيِّ صلى الله عليه وسلم يَحْكِي نَبِيًّا مِنَ الأَنْبِيَاءِ ضَرَبَهُ قَوْمُهُ فَأَدْمَوْهُ، وَهْوَ يَمْسَحُ الدَّمَ عَنْ وَجْهِهِ، وَيَقُولُ ‏
"‏ اللَّهُمَّ اغْفِرْ لِقَوْمِي فَإِنَّهُمْ لاَ يَعْلَمُونَ ‏"‏‏.‏
