Ali bin Ms'hr علي بن مسهر · The Book of Water

"The Messenger of Allah (ﷺ) would say: 'Allahummaghsil khatayaya bi-ma'ith-thalj wal-barad (O Allah, wash away my sins with the water of snow and hail).'" That is at the beginning of Salah as is clear from the remainder of the narration which preceded under No. 60.
