Musnad Ahmad 769:17

Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, from Mujza’ah ibn Zahir; and Hajjaj narrated to me, Shu‘bah narrated to me, from Mujza’ah ibn Zahir; and Rawh narrated to us, they said: Shu‘bah narrated to us, from Mujza’ah ibn Zahir, a freed slave of Quraysh, who said: I heard ‘Abdullah ibn Abi Awfa, from the Prophet, may Allah bless him and grant him peace, that he used to say: "O Allah, to You is the praise, filling the heavens, and filling the earth, and filling whatever You will of anything after that. O Allah, purify me with snow, hail, and cold water. O Allah, purify me from sins, and cleanse me of them just as a white garment is cleansed of filth."
