Entering the prayer with the imam in an extra rak'ah
Machine translationRead the Arabic original
Question:
This man says: If a ma'mum (one praying behind the imam) joins the imam in the last rak'ah of the Zuhr prayer, and after the prayer it becomes clear that it was the fifth rak'ah, because the congregation alerted him, does this rak'ah count as a rak'ah for him, or does he not build upon this rak'ah?
Answer:
He does not build upon the extra rak'ah. The extra rak'ah is not a prayer, and he does not build upon it. He performs a rak'ah in its place. Yes.
