حَدَّثَنَا الْحَسَنُ بْنُ الرَّبِيعِ حَدَّثَنَا أَبُو الْأَحْوَصِ عَنْ عَاصِمٍ عَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ بَعَثَ النَّبِيُّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ سَرِيَّةً يُقَالُ لَهُمْ الْقُرَّائُ فَأُصِيبُوا فَمَا رَأَيْتُ النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ وَجَدَ عَلَی شَيْئٍ مَا وَجَدَ عَلَيْهِمْ فَقَنَتَ شَهْرًا فِي صَلَاةِ الْفَجْرِ وَيَقُولُ إِنَّ عُصَيَّةَ عَصَوْا اللَّهَ وَرَسُولَهُ
صحیح بخاری · Hadith 6394
Narrated Anas: The Prophet sent a Sariya (an army detachment) consisting of men called Al-Qurra', and all of them were martyred. I had never seen the Prophet so sad over anything as he was over them. So he said Qunut (invocation in the prayer) for one month in the Fajr prayer, invoking for Allah's wrath upon the tribe of 'Usaiya, and he used to say, "The people of 'Usaiya have disobeyed Allah and His Apostle."
