The above (No 868) tradition has also been reported through a different chain of narrators by Uqbah ibn Amir to the same effect. This version adds: When the Messenger of Allah ﷺ bowed, he said: "Glory and praise be to my mighty Lord" three times, and when he prostrated himself, he said: "Glory and praise be to my most high Lord" three times. Abu Dawud said: We are afraid the addition of the word "praise" is not guarded.
فَكَانَ رَسُولُ اللَّهِ ﷺ إِذَا رَكَعَ قَالَ سُبْحَانَ رَبِّيَ الْعَظِيمِ وَبِحَمْدِهِ ثَلاَثًا وَإِذَا سَجَدَ قَالَ سُبْحَانَ رَبِّيَ الأَعْلَى وَبِحَمْدِهِ ثَلاَثًا
