Question: Assalam alaykum
If the Imam does not perform the prostration of forgetfulness despite making a mistake does this require that prayer to be made up?
The mistake was sitting in the third cycle instead of standing. A follower said Allahuakbar to remind him to stand.
Answer: Assalamu alaikum wa rahmatullah,
In the case that the imam does something necessitating the prostrations of forgetfulness (sajda al-sahw), yet he does not proceed to prostrate, it would seem that the prayer is to be repeated.
The general principle is that every prayer which is prayed in a deficient manner is to be repeated to correct the error. The specific ruling of the repetition, however, depends upon the circumstance at hand.
