Question:
May Allah reward you, Honorable Shaykh. This questioner says: I said Allahu Akbar with the imam while he was rising from the bowing. I made a mistake, and instead of saying, “Our Lord, to You belongs all praise,” I recited the opening supplication by mistake. What is the ruling on that?
Answer:
If you did not do it intentionally, there is nothing wrong with it. You would have been required to perform the prostration for forgetfulness, but you are following the imam, and the imam bears that responsibility. Yes.
