Musannaf Ibn Abi Shaybah 31169 — The supplication of the Prophet

Sayyiduna Abu Hurayrah (may Allah be pleased with him) said that when the Messenger of Allah (peace and blessings be upon him) said the takbir for prayer, he would remain silent for a while between the takbir and the recitation. Abu Hurayrah said: I asked him (peace and blessings be upon him): "May my father and mother be sacrificed for you! I see you (peace and blessings be upon him) remaining silent between the takbir and the recitation; tell me (peace and blessings be upon him), what do you (peace and blessings be upon him) recite?" He (peace and blessings be upon him) said: "I recite this supplication: O Allah! Put between me and my sins a distance as long as that between the East and the West. O Allah! Purify and cleanse me of my sins just as a white garment is purified and cleansed of dirt. O Allah! Wash my sins from me with water, hail, and snow."
