Narrated `Aisha:The Prophet (ﷺ) used to say frequently in his bowing and prostrations "Subhanaka l-lahumma Rabbana wa bihamdika, Allahumma ghfir li" (Exalted [from unbecoming attributes] Are you O Allah our Lord, and by Your praise [do I exalt you]. O Allah! Forgive me). In this way [??] he was acting on what was explained to him in the Holy Qur'an
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
