And the clarification that it is to be said after raising the head from bowing in the final rak`ah, and it is recommended to say it out loud
وَحَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ، وَأَبُو كُرَيْبٍ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ وَمُحَمَّدُ بْنُ عَبْدِ الأَعْلَى - وَاللَّفْظُ لاِبْنِ مُعَاذٍ - حَدَّثَنَا الْمُعْتَمِرُ بْنُ سُلَيْمَانَ، عَنْ أَبِيهِ، عَنْ أَبِي مِجْلَزٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَنَتَ رَسُولُ اللَّهِ صلى الله عليه وسلم شَهْرًا بَعْدَ الرُّكُوعِ فِي صَلاَةِ الصُّبْحِ يَدْعُو عَلَى رِعْلٍ وَذَكْوَانَ وَيَقُولُ عُصَيَّةُ عَصَتِ اللَّهَ وَرَسُولَهُ .
Anas b. Malik reported: The Messenger of Allah (ﷺ) observed Qunut for a month in the dawn prayer after ruku' and invoked curse upon Ri'l, Dhakwan, and said that 'Usayya had disobeyed Allah and His Messenger (ﷺ).
