The ruling on praying behind a traveler?

Question : The questioner asks: Is it permissible for the residents to pray behind a traveler who shortens the prayer, and then for them to complete the remainder after the prayer?

Answer : The answer is yes, it is permissible for the traveler to be the imam for the residents. When he says the closing salam, the residents stand up and complete the prayer after him. However, the traveler who leads the residents should inform them before praying. He should say to them, "We are travelers, so when we say the salam, complete your prayer." This is because the Prophet (peace and blessings be upon him) prayed with the people of Makkah in the year of the Conquest and said to them, "Complete your prayer, O people of Makkah, for we are a traveling group." So he would pray two rak'ahs with them, and they would complete four rak'ahs after him.
