Sunan Ibn Majah, Book 36, Hadith 102 (In-Book) ⓘ

It was narrated that Anas bin Malik said: On the Day of Uhud, a molar of the Messenger of Allah was broken and he was wounded. Blood started pouring down his face, and he started to wipe his face and say: “How can any people prosper if they soak the face of their Prophet with blood when he is calling them to Allah?” Then Allah revealed: “Not for you is the decision.”[3:128]

حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، قَالاَ حَدَّثَنَا عَبْدُ الْوَهَّابِ، حَدَّثَنَا حُمَيْدٌ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ لَمَّا كَانَ يَوْمُ أُحُدٍ كُسِرَتْ رَبَاعِيَةُ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ وَشُجَّ فَجَعَلَ الدَّمُ يَسِيلُ عَلَى وَجْهِهِ وَجَعَلَ يَمْسَحُ الدَّمَ عَنْ وَجْهِهِ وَيَقُولُ ‏ "‏ كَيْفَ يُفْلِحُ قَوْمٌ خَضَبُوا وَجْهَ نَبِيِّهِمْ بِالدَّمِ وَهُوَ يَدْعُوهُمْ إِلَى اللَّهِ ‏" ‏ ‏.‏ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ ‏{لَيْسَ لَكَ مِنَ الأَمْرِ شَىْءٌ}‏ ‏.‏
