The Ruling on the Prayer of a Ma'mum Behind an Imam Who Added a Rak'ah
Machine translationRead the Arabic original
Question:
This man is asking, may Allah bless you. Muhammad says: The imam prayed five rak'ahs for the 'Isha' prayer, and I prayed four rak'ahs with him because I was masbuq (one who joins the prayer late) by one rak'ah. Is my prayer complete and valid?
Answer:
Do not count the extra rak'ah, because it is not part of the prayer. So, perform the rak'ah that you missed, and do not count this extra one. Yes.
The presenter:
Yes, may Allah bless you.
