Sahih Muslim Book - 5, Hadith - 1558

وَحَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ وَقُتَيْبَةُ وَابْنُ حُجْرٍ قَالَ ابْنُ أَيُّوبَ حَدَّثَنَا إِسْمَاعِيلُ قَالَ أَخْبَرَنِى مُحَمَّدٌ - وَهُوَ ابْنُ عَمْرٍو - عَنْ خَالِدِ بْنِ عَبْدِ اللَّهِ بْنِ حَرْمَلَةَ عَنِ الْحَارِثِ بْنِ خُفَافٍ أَنَّهُ قَالَ قَالَ خُفَافُ بْنُ إِيمَاءٍ رَكَعَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- ثُمَّ رَفَعَ رَأْسَهُ فَقَالَ « غِفَارُ غَفَرَ اللَّهُ لَهَا وَأَسْلَمُ سَالَمَهَا اللَّهُ وَعُصَيَّةُ عَصَتِ اللَّهَ وَرَسُولَهُ اللَّهُمَّ الْعَنْ بَنِى لِحْيَانَ وَالْعَنْ رِعْلاً وَذَكْوَانَ ». ثُمَّ وَقَعَ سَاجِدًا. قَالَ خُفَافٌ فَجُعِلَتْ لَعْنَةُ الْكَفَرَةِ مِنْ أَجْلِ ذَلِكَ.

It was narrated that Al-Harith bin Khufaf said: "Khufaf bin Ima' said: 'The Messenger of Allah (s.a.w) bowed, then he raised his head and said: "May Allah forgive Ghifar and may Allah grant protection to Aslam. 'Usayyah have disobeyed Allah and His Messenger. O Allah, curse Banu Lihyan and curse Ri'l and Dhakwan." Then he prostrated.' Khufat said: 'Cursing the disbelievers was prescribed as a result of that.'"
