'Aishah (May Allah be pleased with her) reported:
The Prophet ﷺ 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)."

[Al-Bukhari and Muslim].

وعن عائشة رضي الله عنه قالت: كان النبي ﷺ يكثر أن يقول في ركوعه وسجوده: سبحانك اللهم ربنا وبحمدك، اللهم اغفر لي" ((متفق عليه)).
