Machine translationRead the Arabic original
Question:
The questioner says: If a man comes from a journey, enters the mosque, and finds the imam praying 'Isha', while he has not yet prayed Maghrib, what should he do?
Answer:
He prays Maghrib, then joins the imam in the remainder of 'Isha. This is especially the case if he is with others who are praying in congregation; they pray the Maghrib congregation first, then catch up with the imam in the remainder of 'Isha. If he is not with a congregation and wants to join the imam while he is praying 'Isha, he intends Maghrib while they are praying 'Isha. When they stand for the fourth rak'ah, he sits and does not stand with them. He then performs the final tashahhud. If he wishes, he says the taslim for himself; if he wishes, he waits and says the taslim with the imam. This is the ruling issued by the Permanent Committee. Yes.
