The ruling for the ma'mum if he forgets something from the obligations of the prayer

Question:
May Allah reward you with good, and may He do you good. If the ma'mum forgets in the prayer while he is behind the imam, the narrated supplication "O Allah, forgive me and have mercy on me" which is in the tashahhud between the two prostrations, does he prostrate twice for forgetfulness after the imam has said the taslim, or does the imam bear that for him? May Allah reward you with good.

Answer:
If he entered the prayer with the imam from the beginning, and he made a mistake by leaving out something from the obligations of the prayer, such as saying "O Allah, forgive me" between the two prostrations, or "Glory be to my Lord, the Most High" in the ruku', or "Glory be to my Lord, the Most Exalted" in the sujud, or he forgot the takbir of transition, then in these cases he does not have to prostrate; the imam bears it for him, because he entered with the beginning of the prayer. For this reason, the jurists say: "There is no prostration for the ma'mum except following his imam." Yes.
