The ruling on a traveler who shortens the prayer behind a resident imam
Machine translationRead the Arabic original
Question:
This is a Sudanese man who says: An imam is praying, and behind this imam is a person who shortens the prayer for the 'Asr prayer. The imam stood up from the second rak'ah, but the traveler sat down and remained seated until the prayer was completed. What is the ruling on that?
Answer:
This is an invalid act, because the ruling of the ma'mum (one praying behind the imam) is the ruling of the imam. So if the traveler joins the one who is completing the prayer, he is required to complete it following his imam. So this man must repeat the prayer that he shortened behind the resident imam who completes the prayer. He must repeat the prayer. Yes.
