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
Anas was asked, "Did the Prophet ﷺ recite Qunut in the Fajr prayer?" Anas replied in the affirmative. He was further asked, "Did he recite Qunut before bowing?" Anas replied, "He recited Qunut after bowing for some time (for one month)."
سُئِلَ أَنَسٌ أَقَنَتَ النَّبِيُّ ﷺ فِي الصُّبْحِ قَالَ نَعَمْ فَقِيلَ لَهُ أَوَقَنَتَ قَبْلَ الرُّكُوعِ قَالَ بَعْدَ الرُّكُوعِ يَسِيرًا
"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."
أَنَّ أَنَسَ بْنَ مَالِكٍ سُئِلَ هَلْ قَنَتَ رَسُولُ اللَّهِ ﷺ فِي صَلاَةِ الصُّبْحِ قَالَ نَعَمْ فَقِيلَ لَهُ قَبْلَ الرُّكُوعِ أَوْ بَعْدَهُ قَالَ بَعْدَ الرُّكُوعِ
"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." (Using translation from Nasāʾī 1071)
أَنَّ أَنَسِ بْنِ مَالِكٍ سُئِلَ هَلْ قَنَتَ رَسُولُ اللهِ ﷺ فِي صَلَاةِ الصُّبْحِ؟ فَقَالَ «نَعَمْ» فَقِيلَ لَهُ قَبْلَ الرُّكُوعِ أَوْ بَعْدَهُ؟ فَقَالَ «بَعْدَ الرُّكُوعِ»
