"My paternal uncle was absent from the fighting of Badr, so he said: 'I was absent from the first fight the Messenger of Allah ﷺ fought with idolaters, so if Allah grants me to participate in a fight with the idolaters, then Allah will see what I will do!' So on the Day of Uhud, when the Muslims were driven back he said: 'O Allah! Indeed I am innocent before you of what these people - meaning the idolaters - have done, and I beg of You to excuse these people for what they have done - meaning the Companions. Then he went forward and met up with Sa'd. He said: 'O my brother! Whatever you do, I am with you!' But he was not able to do the same as him. He was found with more than eighty wounds, between blows with the sword, thrusts of a spear, or arrow wounds. We would say: 'It was about him and his companions that (the following) was revealed: 'Of them some have fulfilled their vow, and some of them are still waiting, but they have never changed in the least (33:23). (One of the narrators) Yazid said: "Meaning this Ayah."
عَنْ أَوَّلِ قِتَالٍ قَاتَلَهُ رَسُولُ اللَّهِ ﷺ الْمُشْرِكِينَ لَئِنِ اللَّهُ أَشْهَدَنِي قِتَالاً لِلْمُشْرِكِينَ لَيَرَيَنَّ اللَّهُ كَيْفَ أَصْنَعُ فَلَمَّا كَانَ يَوْمُ أُحُدٍ انْكَشَفَ الْمُسْلِمُونَ فَقَالَ اللَّهُمَّ إِنِّي أَبْرَأُ إِلَيْكَ مِمَّا جَاءَ بِهِ هَؤُلاَءِ يَعْنِي الْمُشْرِكِينَ وَأَعْتَذِرُ إِلَيْكَ مِمَّا يَصْنَعُ هَؤُلاَءِ يَعْنِي أَصْحَابَهُ ثُمَّ تَقَدَّمَ فَلَقِيَهُ سَعْدٌ فَقَالَ يَا أَخِي مَا فَعَلْتَ أَنَا مَعَكَ فَلَمْ أَسْتَطِعْ أَنْ أَصْنَعَ مَا صَنَعَ فَوُجِدَ فِيهِ بِضْعٌ وَثَمَانُونَ مِنْ ضَرْبَةٍ بِسَيْفٍ وَطَعْنَةٍ بِرُمْحٍ وَرَمْيَةٍ بِسَهْمٍ فَكُنَّا نَقُولُ فِيهِ وَفِي أَصْحَابِهِ نَزَلَتْ (فمِنْهُمْ مَنْ قَضَى نَحْبَهُ وَمِنْهُمْ مَنْ يَنْتَظِرُ ) قَالَ يَزِيدُ يَعْنِي هَذِهِ الآيَةَ
