"The Messenger of Allah ﷺ often used to say when bowing and prostrating: 'Subhanaka Rabbana wa bi Hamdika, Allahumm aghfirli (Glorfy and praise be to You, our Lord. O Allah, forgive me.).'" (Using translation from Nasāʾī 1047)
كَانَ رَسُولُ اللهِ ﷺ يُكْثِرُ أَنْ يَقُولُ فِي رُكُوعِهِ وَسُجُودِهِ «سُبْحَانَكَ رَبِّنَا وَبِحَمْدِكَ اللهُمَّ اغْفِرْ لِي»
