Machine translationRead the Arabic original
Question:
Also, the righteous brother asks, saying: What is the ruling if the ma'mum forgets a pillar of the prayer, such as reciting the final tashahhud? Does he say the taslim with the imam, or does he make up the pillar?
Answer:
It is not permissible for him to say the taslim with the imam, because his prayer is not complete. He should recite the final tashahhud, lagging behind the imam, and then, once he has completed it, he says the taslim for himself. Yes.
