Narrated 'Aisha:

The Prophet used to say frequently in his bowing and prostrations "Subhanaka-Allahumma Rabbana Wabihamdika, Allahumma Ighfir-li" (I honor Allah from all what (unsuitable things) is ascribed to Him, O Allah! Our Lord! All praises are for You. O Allah! Forgive me). In this way he was acting on what was explained to him in the Holy Qur'an.

حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ سُفْيَانَ، قَالَ حَدَّثَنِي مَنْصُورٌ، عَنْ مُسْلِمٍ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّهَا قَالَتْ كَانَ النَّبِيُّ ﷺ يُكْثِرُ أَنْ يَقُولَ فِي رُكُوعِهِ وَسُجُودِهِ " سُبْحَانَكَ اللَّهُمَّ رَبَّنَا وَبِحَمْدِكَ، اللَّهُمَّ اغْفِرْ لِي " يَتَأَوَّلُ الْقُرْآنَ.
