Musnad Abu Ya'la al-Mawsili 107:1

Abu Bakr ibn Abi Shaybah narrated to us, Abu Usamah narrated to us, Sufyan narrated to us, from Mu'awiyah ibn Salih, from Abd al-Rahman ibn Jubayr ibn Nufayr, from his father, from Uqbah ibn Amir: That he asked the Prophet, peace and blessings of Allah be upon him, about the two *Mu'awwidhatayn* (the two surahs of seeking refuge). Uqbah said: So the Messenger of Allah, peace and blessings of Allah be upon him, led us in prayer with them during the dawn prayer. Then he called me, and I mentioned his hadith regarding them.
