Musannaf Ibn Abi Shaybah 6390 — The new mosque and the old

Awf said: A man from the desert people told me that in the time of Sayyiduna Mu'awiyah (may Allah be pleased with him) his representative came to us to collect the zakah. One day he was sitting at our water spring when the time of prayer came. At that spring there were two mosques of the desert people. He asked: Which of these mosques was built first? He was told, and he went to that mosque.
