A man who recites a verse of prostration, errs and adds another: whether he prostrates for forgetfulness

Mughirah said: I asked Ibrahim: "If I recite a verse of prostration and, while prostrating, forgetfully add another prostration to it, what is the ruling for me?" He said: "Then perform the two prostrations of forgetfulness as well."

Concerning a man who recites a verse of prostration during an obligatory prayer and then performs two prostrations, al-Hasan said: He should also perform the two prostrations of forgetfulness after he finishes.

Ubaydullah bin Abi Ziyad said: I asked Sa'id bin Jubayr: "If I recite a verse of prostration while I am in prostration, should I prostrate?" He said: "No. But why do you recite a verse of prostration while in prostration?"
