حَدَّثَنَا عَبْدُ الصَّمَدِ وَعَفَّانُ قَالَا حَدَّثَنَا ثَابِتٌ عَنْ هِلَالٍ عَنْ عِكْرِمَةَ عَنِ ابْنِ عَبَّاسٍ قَالَ قَنَتَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ شَهْرًا مُتَتَابِعًا فِي الظُّهْرِ وَالْعَصْرِ وَالْمَغْرِبِ وَالْعِشَاءِ وَالصُّبْحِ فِي دُبُرِ كُلِّ صَلَاةٍ إِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ مِنْ الرَّكْعَةِ الْأَخِيرَةِ يَدْعُو عَلَيْهِمْ عَلَى حَيٍّ مِنْ بَنِي سُلَيْمٍ عَلَى رِعْلٍ وَذَكْوَانَ وَعُصَيَّةَ وَيُؤَمِّنُ مَنْ خَلْفَهُ أَرْسَلَ إِلَيْهِمْ يَدْعُوهُمْ إِلَى الْإِسْلَامِ فَقَتَلُوهُمْ قَالَ عَفَّانُ فِي حَدِيثِهِ قَالَ وَقَالَ عِكْرِمَةُ هَذَا كَانَ مِفْتَاحَ الْقُنُوتِ
مسند امام احمد بن حنبل · Hadith 2746
It was narrated that Ibn 'Abbas (RA) said: The Messenger of Allah (PBUH) prayed Qunoot every day for an entire month, at Zuhr, 'Asr, Maghrib, 'Isha' and Fajr, at the end of every' prayer. When he said, " Sami' allahu liman hamidah" in the final rak'ah, he would pray against them, against a clan of Banu Sulaim, against RiT, Dhakwan and 'Usayyah, and those who were behind him would say Ameen. He sent (envoys) to them, to call them to Islam, and they killed them. 'Affan said in his hadecth: And 'Ikrimah said: This was the beginning of Qunoot.
