The Traveler Leading the Residents and Completing the Two Rak'ahs

Question:
May Allah reward you, Honorable Shaykh. This questioner says: A man who is traveling led a group of residents in the midday prayer, then he said the closing salam after two rak'ahs. Is it permissible for one of them to step forward and lead the congregation in the last two rak'ahs, or do they pray individually, each making up the remaining two rak'ahs on his own?

Answer:
If everyone knows that the Prophet (peace and blessings be upon him), when he prayed and left them in the mosque in the Chamber of Farewell, prayed with them in the Sacred Precinct, and said: When the Prophet (peace and blessings be upon him) said the closing salam, they stood up and completed the prayer for themselves, and they did not appoint an imam. So, each one completes it for himself. It is not mentioned that he appointed an imam; rather, each one completed it for himself. They become like the responsible ones.
