Musnad Ahmad 30:848

Muhammad ibn Ja‘far and Hashim narrated to us, they said: Shu‘bah narrated to us, from Abu Balj—Hashim said: Yahya ibn Abi Sulaym informed me—he said: I heard ‘Amr ibn Maymun, he said: I heard Abu Hurayrah narrating from the Prophet, may Allah bless him and grant him peace, that he said: "Shall I not teach you—Hashim said: Shall I not guide you—to a word from the treasure of Paradise from beneath the Throne: 'There is no power except by Allah' (La hawla wa la quwwata illa billah)? He says: My servant has submitted and surrendered."
