By Allah, I shall offer prayer like that of the Messenger of Allah ﷺ. The narrator said: Abu Hurairah used to recite the supplication in the last rak'ah of the noon, night and dawn prayers. He would supplicate for the believers and curse the disbelievers.  

وَاللَّهِ لأُقَرِّبَنَّ بِكُمْ صَلاَةَ رَسُولِ اللَّهِ ﷺ قَالَ فَكَانَ أَبُو هُرَيْرَةَ يَقْنُتُ فِي الرَّكْعَةِ الآخِرَةِ مِنْ صَلاَةِ الظُّهْرِ وَصَلاَةِ الْعِشَاءِ الآخِرَةِ وَصَلاَةِ الصُّبْحِ فَيَدْعُو لِلْمُؤْمِنِينَ وَيَلْعَنُ الْكَافِرِينَ  

The Prophet ﷺ used to recite the supplication in the dawn prayer. The version of Ibn Mu'adh has the words: "sunset prayer".  

أَنَّ النَّبِيَّ ﷺ كَانَ يَقْنُتُ فِي صَلاَةِ الصُّبْحِ زَادَ ابْنُ مُعَاذٍ وَصَلاَةِ الْمَغْرِبِ  

The Messenger of Allah ﷺ recited the supplication in the night prayer for a month. He said (in his supplication): O Allah, rescue al-Walid b. al-Walid, rescue Salamah b. Hisham, rescue the weak believers; O Allah, trample severely on Mudar; O Allah, cause them a famine like that of Joseph. Abu Hurairah said: One morning the Messenger of Allah ﷺ id not make supplication for them. So I told him about it. He said: You dod not see that they have come (back).  

قَنَتَ رَسُولُ اللَّهِ ﷺ فِي صَلاَةِ الْعَتَمَةِ شَهْرًا يَقُولُ فِي قُنُوتِهِ اللَّهُمَّ نَجِّ الْوَلِيدَ بْنَ الْوَلِيدِ اللَّهُمَّ نَجِّ سَلَمَةَ بْنَ هِشَامٍ اللَّهُمَّ نَجِّ الْمُسْتَضْعَفِينَ مِنَ الْمُؤْمِنِينَ اللَّهُمَّ اشْدُدْ وَطْأَتَكَ عَلَى مُضَرَ اللَّهُمَّ اجْعَلْهَا عَلَيْهِمْ سِنِينَ كَسِنِي يُوسُفَ قَالَ أَبُو هُرَيْرَةَ وَأَصْبَحَ رَسُولُ اللَّهِ ﷺ ذَاتَ يَوْمٍ فَلَمْ يَدْعُ لَهُمْ فَذَكَرْتُ ذَلِكَ لَهُ فَقَالَ وَمَا تَرَاهُمْ قَدْ قَدِمُوا  

The Messenger of Allah ﷺ 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.  

قَنَتَ رَسُولُ اللَّهِ ﷺ 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  

Anas b. Malik was asked whether the Messenger of Allah ﷺ had recited supplication in the dawn prayer. He replied: Yes. He was again asked whether before bowing or after bowing. He said after bowing. This version of Musaddad adds the words: "For a short period."  

أَنَّهُ سُئِلَ هَلْ قَنَتَ رَسُولُ اللَّهِ ﷺ فِي صَلاَةِ الصُّبْحِ فَقَالَ نَعَمْ فَقِيلَ لَهُ قَبْلَ الرُّكُوعِ أَوْ بَعْدَ الرُّكُوعِ قَالَ بَعْدَ الرُّكُوعِ قَالَ مُسَدَّدٌ بِيَسِيرٍ  

The Prophet ﷺ recited the supplication for a month (in prayer) and then gave it up.  

أَنَّ النَّبِيَّ ﷺ قَنَتَ شَهْرًا ثُمَّ تَرَكَهُ  

Muhammad ibn Sirin said: Someone who prayed the morning prayer along with the Prophet ﷺ narrated to me: When he raised his head after the second rak'ah, he remained standing for a short while.  

حَدَّثَنِي مَنْ صَلَّى مَعَ النَّبِيِّ ﷺ صَلاَةَ الْغَدَاةِ فَلَمَّا رَفَعَ رَأْسَهُ مِنَ الرَّكْعَةِ الثَّانِيَةِ قَامَ هُنَيَّةً
