`Abdullah bin [Abi] Awfa narrated that the Messenger of Allah (ﷺ) used to say:
“O Allah, cool my heart with snow and hail and cold water. O Allah, cleanse my heart of sins as You cleanse a white garment of filth (Allāhumma barrid qalbī bith-thalji wal-baradi wal-mā’il-bārid. Allāhumma naqqi qalbī min al-khaṭāyā kamā naqqaitath-thawbal-abyaḍa min ad-dannas).
