عَنْ عَائِشَةَ رَضِيَ اللّهُ عنْهَا قَالَتْ: كانَ النَّبِيُّ صَلَّى اللّهُ عَلَيْهِ وَسَلَّمَ يُكْثِرُ أنْ يَقُولَ فِي رُكُوعِهِ وَسُجُودِهِ: «سُبْحَانَكَ اللَّهُمَّ رَبَّنَا وَبِحَمْدِكَ، اللَّهُمَّ اغْفِرْ لِي» مُتَّفَقٌ عَلَيْهِ.

Aisha (may Allah be pleased with her) reported: The Prophet (peace and blessings be upon him) used to say frequently in his bowing and prostration: "Glory be to You, O Allah our Lord, and praise be to You. O Allah, forgive me." Agreed upon (al-Bukhari and Muslim).
