It is narrated from Hazrat Ibn Abi Awfa (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) used to say: O Allah, all praise is for You alone, equal to the fullness of the earth and the heavens, and equal to the fullness of whatever else You will. O Allah! Purify me with snow, hail, and cold water. O Allah! Cleanse me of sins just as a white garment is cleansed of dirt.
