Question:
And if he joins them in the third rak'ah, does he pray the two rak'ahs with them and then complete the third after the imam's taslim with the intention of Maghrib? This is a point of difficulty. The one who prays Maghrib alone, or with those who are like him in travel, then joins the imam in the prayer of 'Isha'.
Answer:
Yes.
