Supplication at the start of the prayer (after takbeer)
اللّهُـمَّ باعِـدْ بَيـني وَبَيْنَ خَطـايايَ كَما باعَدْتَ بَيْنَ المَشْرِقِ وَالمَغْرِبْ ، اللّهُـمَّ نَقِّنـي مِنْ خَطايايَ كَمـا يُـنَقَّى الثَّـوْبُ الأَبْيَضُ مِنَ الدَّنَسْ ، اللّهُـمَّ اغْسِلْنـي مِنْ خَطايـايَ بِالثَّلـجِ وَالمـاءِ وَالْبَرَدْ
O Allah, distance me from my sins just as You have distanced The East from The West, O Allah, purify me of my sins as a white robe is purified of filth, O Allah, cleanse me of my sins with snow, water, and ice.
