Musnad Ahmad 435:62

Muhammad ibn Fudayl narrated to us, he said: Uthman ibn Hakim narrated to us, he said: I heard Muhammad ibn Ka’b al-Qurazi, he said: I heard Mu’awiyah saying: I heard the Messenger of Allah, may Allah bless him and grant him peace, saying when he finished the prayer: "O Allah, there is no preventer for what You have given, and no giver for what You have prevented, and the wealth of the wealthy will not benefit him against You."
