Imam (as) said: "A resident (non-traveler) should not lead a traveler, nor should a traveler lead a resident. If a man finds himself in a situation where he must lead a congregation of residents and completes two rak'ahs, he should then offer the taslim (salutation of peace), take the hand of one of the residents, and place him to lead the rest. When a traveler prays behind a group of residents, he should complete his prayer with two rak'ahs and then offer the taslim."
