اَللّٰهُمَّ اغْسِلْ قَلْبِیْ بِمَاءِ الثَّلْجِ وَالْبَرَدِ وَنَقِّ قَلْبِیْ مِنَ الْخَطَایَا كَمَا نَقَّیْتَ الثَّوْبَ الْأَبْیَضَ مِنَ الدَّنَسِ وَبَاعِدْ بَیْنِیْ وَبَیْنَ خَطَایَایَ كَمَا بَاعَدْتَ بَیْنَ الْمَشْرِقِ وَالْمَغْرِبِ
“O Allah, wash my heart with the water of snow and hail, and cleanse my heart from sins as You cleanse a white garment from dirt, and keep me away from my sins as You have kept the east far from the west.”
(Sahih al-Bukhari: 6377)
