question #1 Sahih Muslim 598a-b, Book 5, Hadith 190 : What supplication did the Prophet Muhammad (ﷺ) make during the silent pause between takbir and Qur’an recitation in prayer?

Messenger of Allah, for whom I would give my father and mother in ransom, what do you recite during your period of silence between the takbir and the recitation? He said: I say (these words):” O Allah, remove my sins from me as Thou hast removed the East from the West. O Allah purify me from sins as a white garment is purified from filth. O Allah! wash away my sins with snow, water, and ice.”
