Pronunciation: Allahumma ba'id bay-ni wa bay-na kha-ta-yaya ka-ma ba'ad-ta bay-nal-mash-riqi wal-maghrib. Allahumma naq-qi-nee mi-nal kha-ta-ya ka-ma yu-naq-qas-thaw-bul ab-ya-du minad-da-nas. Allahummagh-sil kha-ta-ya-ya bil-ma'i wath-thal-ji wal-ba-rad.
Meaning: O Allah! Set me apart from my sins (faults) as the East and West are set apart from each other and clean me from sins as a white garment is cleaned of dirt (after thorough washing). O Allah! Wash off my sins with water, snow and hail.
