I heard from Sayyiduna Usama bin Zaid (may Allah be pleased with him), he said that the Messenger of Allah (peace and blessings of Allah be upon him) returned from the plain of Arafat. When he reached the valley, he dismounted. The Prophet (peace be upon him) relieved himself, then performed ablution, but did not do it thoroughly. Then I said, "O Messenger of Allah! The time for prayer (has come)." The Prophet (peace be upon him) said, "The prayer is ahead of you (i.e., we will pray after reaching Muzdalifah)." When he reached Muzdalifah, he performed ablution thoroughly, then the congregation was established, and the Prophet (peace be upon him) led the Maghrib prayer. Then everyone made their camels sit at their places, then the congregation for Isha was established and the Prophet (peace be upon him) led the prayer, and between these two prayers, he did not perform any other prayer.
