Muhammad reported:

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."

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، وَمُسَدَّدٌ، قَالاَ حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، عَنْ مُحَمَّدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، 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 .
