حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُعَاوِيَةَ الْجُمَحِيُّ، حَدَّثَنَا ثَابِتُ بْنُ يَزِيدَ، عَنْ هِلاَلِ بْنِ خَبَّابٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَنَتَ رَسُولُ اللَّهِ صلى الله عليه وسلم شَهْرًا مُتَتَابِعًا فِي الظُّهْرِ وَالْعَصْرِ وَالْمَغْرِبِ وَالْعِشَاءِ وَصَلاَةِ الصُّبْحِ فِي دُبُرِ كُلِّ صَلاَةٍ إِذَا قَالَ ‏"‏ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ ‏"‏ ‏.‏ مِنَ الرَّكْعَةِ الآخِرَةِ يَدْعُو عَلَى أَحْيَاءٍ مِنْ بَنِي سُلَيْمٍ عَلَى رِعْلٍ وَذَكْوَانَ وَعُصَيَّةَ وَيُؤَمِّنُ مَنْ خَلْفَهُ ‏.‏

Narrated Abdullah ibn Abbas: The Messenger of Allah (PBUH) recited the supplication (Qunut) daily for a month at the noon, afternoon, sunset, night and morning prayers. When he said: "Allah listens to him who praises Him" in the last rak'ah, invoking a curse on some clans of Banu Sulaym, Ri'l, Dhakwan and Usayyah, and those who were standing behind him said: Amen.
