وعن عائشة رضي الله عنه
قالت: كان النبي صلى الله عليه وسلم يكثر أن يقول في ركوعه وسجوده: سبحانك اللهم ربنا وبحمدك، اللهم اغفر لي
The Prophet (sallallahu alayhi wa sallam) used to recite frequently in his bowing and prostration: “Subhanak- Allahumma, Rabbana wa bihamdika. Allahum-maghfir li (O Allah! You are free from imperfection and I begin with praising You. Forgive my sins).”.
