Sahih Muslim 676
Abu Salama b. 'Abd al-Rahman is reported to have said that he had heard Abu Huraira saying: I would say prayer along with you which is near to the prayer of the Messenger of Allah ﷺ. and Abu Huraira recited Qunut in the noon and in the 'Isya' and in the morning prayer, and invoked blessing (of Allah) upon Muslims-and curse upon the unbelievers.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، حَدَّثَنِي أَبِي، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، قَالَ حَدَّثَنَا أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ، أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ وَاللَّهِ لأُقَرِّبَنَّ بِكُمْ صَلاَةَ رَسُولِ اللَّهِ ﷺ . فَكَانَ أَبُو هُرَيْرَةَ يَقْنُتُ فِي الظُّهْرِ وَالْعِشَاءِ الآخِرَةِ وَصَلاَةِ الصُّبْحِ وَيَدْعُو لِلْمُؤْمِنِينَ وَيَلْعَنُ الْكُفَّارَ .
