O Allah! our Lord, unto Thee be praise that would fill the heavens and the earth and fill that which will please Thee besides (them). O Allah! purify me with snow, (water of) hail and with cold water; O Allah. cleanse me from the sins and errors just as a white garment is cleansed from dirt. (Using translation from Muslim 476c)
عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ يَقُولُ اللهُمَّ لَكَ الْحَمْدُ مِلْءَ السَّمَاءِ وَمِلْءَ الْأَرْضِ وَمِلْءَ مَا شِئْتَ مِنْ شَيْءٍ بَعْدُ اللهُمَّ طَهِّرْنِي بِالثَّلْجِ وَالْبَرَدِ وَالْمَاءِ الْبَارِدِ اللهُمَّ طَهِّرْنِي مِنَ الذُّنُوبِ وَنَقِّنِي مِنْهَا كَمَا يُنَقَّى الثَّوْبُ الْأَبْيَضُ مِنَ الْوَسَخِ
