Musnad Abu Ya'la al-Mawsili 108:60

Abu Khaythama narrated to us, Sufyan ibn 'Uyaynah narrated to us, he heard 'Amr from Jabir, who said: Mu'adh used to pray with the Prophet, peace and blessings of Allah be upon him, then he would return and lead his people in prayer. One night, the Prophet, peace and blessings of Allah be upon him, delayed the prayer, so he (Mu'adh) came and recited Surat al-Baqarah. The Prophet, peace and blessings of Allah be upon him, said to him: "Are you a tempter, O Mu'adh?"
