If the imam omits the prostration for forgetfulness and does not prostrate, does the ma'mum prostrate? - Ibn

Question : He says: If the imam prays and makes a mistake in his prayer, and does not perform the prostration for forgetfulness, and he finishes his prayer without being reminded, is it permissible for us to perform the prostration for forgetfulness after the completion of the prayer?

Answer : Yes, if the imam omits the prostration for forgetfulness, whether due to forgetfulness or because he broke his ritual purity after the prayer, for example, or something similar, then the ma'mum prostrates if he gives up hope of the imam prostrating. This is because the forgetfulness of the imam, I mean the imam's forgetfulness, is a forgetfulness that applies to the imam and to those behind him. The forgetfulness of the ma'mum is not a forgetfulness that applies to the imam. Pay attention to two rules: the forgetfulness of the imam applies to him and to those behind him, and the forgetfulness of the ma'mum is not a forgetfulness that applies to the imam.
So if the imam omits saying "Subhan Rabbi al-A'la" (Glory be to my Lord, the Most High) in the prostration, he has omitted an obligatory act, and it is obligatory for him to perform the prostration for forgetfulness. Here, if the imam prostrates, it is obligatory for the ma'mum to prostrate with him, following him. If the ma'mum forgets to say "Subhan Rabbi al-A'la" in the prostration and nothing of the prayer is missed for him, he says the closing salam with the imam, and he has no prostration for forgetfulness to perform; the imam bears it for him. So the ma'mum bears the imam's forgetfulness if nothing of the prayer is missed for him. And the imam? The imam's forgetfulness is upon him and upon those behind him. Yes.
