"The Prophet ﷺ used to say: 'Allahumaghsil khatayaya bi-ma'ith-thalj wal-barad was naqqi qalbi min al-khataya kama naqayta ath-thawb al-abyad min ad-danas (O Allah, was away my sins with the water of snow and hail, and cleanse my heart of sin as a white garment is cleansed of filth.'" (Using translation from Nasāʾī 61)  

الكبرى للنسائي:٥٩أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ قَالَ أَخْبَرَنَا جَرِيرٌ عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ عَائِشَةَ قَالَتْ

كَانَ رَسُولُ اللهِ ﷺ يَقُولُ «اللهُمَّ اغْسِلْ خَطَايَايَ بِمَاءِ الثَّلْجِ وَالْبَرَدِ وَنَقِّ قَلْبِي مِنَ الْخَطَايَا كَمَا نَقَّيْتَ الثَّوْبَ الْأَبْيَضَ مِنَ الدَّنَسِ»
