Imam Bukhari : 3955بَاب حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا غُنْدَرٌ حَدَّثَنَا شُعْبَةُ عَنْ مَنْصُورٍ عَنْ أَبِي الضُّحَى عَنْ مَسْرُوقٍ عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْكَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ فِي رُكُوعِهِ وَسُجُودِهِ سُبْحَانَكَ اللَّهُمَّ رَبَّنَا وَبِحَمْدِكَ اللَّهُمَّ اغْفِرْ لِي
"Narrated to me Muhammad bin Bashar, narrated to us Ghundar, narrated to us Shu'bah from Manshur from Abu Duha from Masruq from Aishah (may Allah be pleased with her), she said, the Prophet peace be upon him used to say in his bowing and prostration, 'Glory be to You, O Allah, our Lord, and with Your praise, O Allah, forgive me.'
