Question:
Honorable Shaykh, a man entered the prayer with the imam and missed a rak'ah. When the imam finished the prayer, he performed two rak'ahs. In this situation, he said "five." What is the ruling?
Answer:
If it was not intentional, it does not invalidate the prayer due to forgetfulness, and his prayer is valid. This extra [rak'ah] was not intentional. Yes.
