Sahih Muslim , Book 19, Hadith 4417 (USC-MSA) ⓘ

It has been narrated on the authority of Anas that the Messenger of Allah had his front teeth damaged on the day of the Battle of Uhud, and got a wound on his head. He was wiping the blood (from his face) and was saying: How will these people attain salvation who have wounded their Prophet and broken his tooth while he called them towards God? At this time, God, the Exalted and Glorious, revealed the Verse:" Thou hast no authority" (iii. 127).

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كُسِرَتْ رَبَاعِيَتُهُ يَوْمَ أُحُدٍ وَشُجَّ فِي رَأْسِهِ فَجَعَلَ يَسْلُتُ الدَّمَ عَنْهُ وَيَقُولُ ‏"‏ كَيْفَ يُفْلِحُ قَوْمٌ شَجُّوا نَبِيَّهُمْ وَكَسَرُوا رَبَاعِيَتَهُ وَهُوَ يَدْعُوهُمْ إِلَى اللَّهِ ‏"‏ ‏.‏ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ ‏{‏ لَيْسَ لَكَ مِنَ الأَمْرِ شَىْءٌ‏}‏
