The traveler praying 'Isha' behind one who is praying Maghrib
Machine translationRead the Arabic original
Question:
The Shaykh’s case and the questioner’s statement. I was traveling, so I prayed the Maghrib prayer with the congregation of the mosque on the road. Then I wanted to shorten the 'Isha' prayer, but I found another group wanting to perform the Maghrib prayer. What must I do? Do I pray Maghrib with them and then say the taslim in the second rak'ah? Or what? Please advise me.
Answer:
If you join them in the Maghrib prayer, you must complete the prayer. You complete the prayer and do not leave it after only two rak'ahs while they are praying.
