Musnad Ahmad 28:483

Rawh narrated to us, Muhammad ibn Abi Humayd narrated to us, Amr ibn Shu’ayb informed me, from his father, from his grandfather, who said: The most frequent supplication of the Messenger of Allah, may Allah bless him and grant him peace, on the day of Arafah was: "There is no god but Allah, alone, He has no partner. To Him belongs the dominion, and to Him belongs the praise. In His hand is all good, and He is capable of all things."
