Sunan an-Nasa'i, Volume 2, Book 12, Hadith 1076 (DarusSalam) ⓘ
It was narrated from Abu Salamah, that Abu Hurairah said: "I shall explain to you the prayer of the Messenger of Allah." He said: "Abu Hurairah used to say the Qunut in the last rak'ah of the Zuhr prayer, and the later Isha' prayer, and the Subh, after saying 'Sami Allahu liman hamidah.' He would pray for the believers and curse the disbelievers.'"
أَخْبَرَنَا سُلَيْمَانُ بْنُ سَلْمٍ الْبَلْخِيُّ، قَالَ حَدَّثَنَا النَّضْرُ، قَالَ أَنْبَأَنَا هِشَامٌ، عَنْ يَحْيَى، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ لأُقَرِّبَنَّ لَكُمْ صَلاَةَ رَسُولِ اللَّهِ صلى الله عليه وسلم . قَالَ فَكَانَ أَبُو هُرَيْرَةَ يَقْنُتُ فِي الرَّكْعَةِ الآخِرَةِ مِنْ صَلاَةِ الظُّهْرِ . وَصَلاَةِ الْعِشَاءِ الآخِرَةِ وَصَلاَةِ الصُّبْحِ بَعْدَ مَا يَقُولُ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَيَدْعُو لِلْمُؤْمِنِينَ وَيَلْعَنُ الْكَفَرَةَ .
