The traveler says the closing salam after two rak'ahs behind a resident imam
Machine translationRead the Arabic original
The questioner:
He prayed with an imam at a station, and this imam completed the prayer. This traveler prayed two rak'ahs, then said the salam, and the imam raised his head from the prostration to complete the prayer. He was asked why he had said the salam? He said: I am a traveler, and I did not complete the prayer with the imam.
The Shaykh:
He is required to make up the prayer. The one who prays around it joins with him. If he prays with the imam, he joins with him. He is required to make up the prayer that he shortened.
