عَنْ أُبَيِّ بْنِ كَعْبٍ رَضِيَ اللَّهُ عَنْهُ قَالَ لَمَّا كَانَ يَوْمُ أُحُدٍ قُتِلَ مِنْ الْأَنْصَارِ أَرْبَعَةٌ وَسِتُّونَ رَجُلًا وَمِنْ الْمُهَاجِرِينَ سِتَّةٌ فَقَالَ أَصْحَابُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَئِنْ كَانَ لَنَا يَوْمٌ مِثْلُ هَذَا مِنْ الْمُشْرِكِينَ لَنُرْبِيَنَّ عَلَيْهِمْ فَلَمَّا كَانَ يَوْمُ الْفَتْحِ قَالَ رَجُلٌ لَا يُعْرَفُ لَا قُرَيْشَ بَعْدَ الْيَوْمِ فَنَادَى مُنَادِي رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَمِنَ الْأَسْوَدُ وَالْأَبْيَضُ إِلَّا فُلَانًا وَفُلَانًا نَاسًا سَمَّاهُمْ فَأَنْزَلَ اللَّهُ تَبَارَكَ وَتَعَالَى {وَإِنْ عَاقَبْتُمْ فَعَاقِبُوا بِمِثْلِ مَا عُوقِبْتُمْ بِهِ وَلَئِنْ صَبَرْتُمْ لَهُوَ خَيْرٌ لِلصَّابِرِينَ} [النحل: 126] فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَصْبِرُ وَلَا نُعَاقِبُ
It is narrated from Sayyiduna Ubayy ibn Ka'b (may Allah be pleased with him) that on the day of Uhud, sixty-four from the Ansar and six men from the Muhajirin were martyred. Some individuals among the Companions said: Now, if we get a chance someday, we will retaliate many times over. Then, when Makkah was conquered, on that day a man said: After today, the name of Quraysh will not remain. But on the other side, the announcer of the Noble Prophet (peace and blessings be upon him) proclaimed: Whether black or white, everyone has been granted safety, except for such and such, mentioning the names of a few people. Then Allah Almighty revealed this verse: {وَإِنْ عَاقَبْتُمْ فَعَاقِبُوْا بِمِثْلِ مَا عُوْقِبْتُمْ بِہِ وَلَئِنْ صَبَرْتُمْ لَہُوَ خَیْرٌ لِلصَّابِرِینَ} … If you retaliate, then retaliate to the extent that you were harmed, but if you are patient, then indeed patience is better for those who are patient. The Noble Prophet (peace and blessings be upon him) said: We will be patient and will not punish.
