Sahih al-Bukhari 6929Book 88, Hadith 11
حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، قَالَ حَدَّثَنِي شَقِيقٌ، قَالَ قَالَ عَبْدُ اللَّهِ كَأَنِّي أَنْظُرُ إِلَى النَّبِيِّ صلى الله عليه وسلم يَحْكِي نَبِيًّا مِنَ الأَنْبِيَاءِ ضَرَبَهُ قَوْمُهُ فَأَدْمَوْهُ، فَهْوَ يَمْسَحُ الدَّمَ عَنْ وَجْهِهِ وَيَقُولُ رَبِّ اغْفِرْ لِقَوْمِي، فَإِنَّهُمْ لاَ يَعْلَمُونَ.
As if I am looking at the Prophet (ﷺ) while he was speaking about one of the prophets whose people have beaten and wounded him, and he was wiping the blood off his face and saying, "O Lord! Forgive my, people as they do not know."
