[Machine] That the Messenger of Allah ﷺ used to say in his bowing, "Subhanarabbial 'aazhim" (Glory be to my Lord, the Most Great), repeatedly. And when he raised his head from bowing, he said, "Sami'allahu liman hamidah, Rabbana wa lakal hamd" (Allah hears whoever praises Him, our Lord, and to You is all praise). And when he prostrated, he said, "Subhanarabbial 'a'la" (Glory be to my Lord, the Most High), repeatedly. And he used to say when he raised his head from prostration, "Rabbighfirli" (My Lord, forgive me).  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَقُولُ فِي رُكُوعِهِ سُبْحَانَ رَبِّيَ الْعَظِيمِ يُرَدِّدُهَا فَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ رَبَّنَا وَلَكَ الْحَمْدُ فَإِذَا سَجَدَ قَالَ سُبْحَانَ رَبِّيَ الْأَعْلَى يُرَدِّدُهَا وَكَانَ يَقُولُ إِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ رَبِّ اغْفِرْ لِي
