Musnad Ahmad 8:182

Rawh narrated to us, Shu'bah narrated to us, from 'Abd al-Malik ibn 'Umayr, who said: I heard Mus'ab ibn Sa'd narrating from his father, Sa'd ibn Abi Waqqas: That he used to command this supplication and narrate it from the Prophet, may Allah bless him and grant him peace: "O Allah, I seek refuge in You from miserliness, and I seek refuge in You from cowardice, and I seek refuge in You from being returned to the vilest of age, and I seek refuge in You from the trial of the world, and I seek refuge in You from the punishment of the grave."
