The Qunut during the Subh prayer
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، عَنِ ابْنِ سِيرِينَ، أَنَّ أَنَسَ بْنَ مَالِكٍ، سُئِلَ هَلْ قَنَتَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي صَلاَةِ الصُّبْحِ قَالَ نَعَمْ . فَقِيلَ لَهُ قَبْلَ الرُّكُوعِ أَوْ بَعْدَهُ قَالَ بَعْدَ الرُّكُوعِ .
It was narrated that Anas bin Malik was asked: "Did the Messenger of Allah (ﷺ) say the Qunut in Subh prayer?" He said: "Yes." He was asked: "Was that before bowing or after?" He said: "After bowing."
