On the Day of Uhud, a molar of the Messenger of Allah ﷺ 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] (Using translation from Ibn Mājah 4027)
لَمَّا كَانَ يَوْمُ أُحُدٍ كُسِرَتْ رَبَاعِيَةُ رَسُولِ اللهِ ﷺ وَشُجَّ فِي وَجْهِهِ قَالَ فَجَعَلَ الدَّمُ يَسِيلُ عَلَى وَجْهِهِ فَجَعَلَ يَمْسَحُ الدَّمَ عَنْ وَجْهِهِ وَيَقُولُ كَيْفَ يُفْلِحُ قَوْمٌ خَضَبُوا وَجْهَ نَبِيِّهِمْ بِالدَّمِ وَهُوَ يَدْعُوهُمْ إِلَى اللهِ قَالَ فَأَنْزَلَ اللهُ {لَيْسَ لَكَ مِنَ الْأَمْرِ شَيْءٌ أَوْ يَتُوبَ عَلَيْهِمْ أَوْ يُعَذِّبَهُمْ فَإِنَّهُمْ ظَالِمُونَ} [آل عمران 128]
