Hisnul Muslim 27

Supplication at the start of the prayer

اللَّهُـمَّ باَعِـدْ بَيْـنِي وَبَيْنَ خَطَـاياَيَ كَماَ باَعَدْتَ بَيْنَ المَشْرِقِ وَالمَغْرِبْ، اللَّهُـمَّ نَقِّنِـي مِنْ خَطَاياَيَ كَمـَا يُـنَقَّى الثَّـوْبُ الأَبْيَضُ مِنَ الدَّنَسْ، اللَّهُـمَّ اغْسِلْنِـي مِنْ خَطَايـَايَ بِالثَّلـجِ وَالمـَاءِ وَالْبَرَدِ

Allaahumma baa'id baynee wa bayna khataayaaya kamaa baa'adta baynal-mashriqi walmaghribi, Allaahumma naqqinee min khataayaaya kamaa yunaqqath-thawbul-'abyadhu minad-danasi, Allaahum-maghsilnee min khataayaaya, bith-thalji walmaa'i walbarad.

O Allah, separate me from my sins as You have separated the East from the West. O Allah, cleanse me of my transgressions as the white garment is cleansed of stains. O Allah, wash away my sins with ice and water and frost.
