Transliteration: Lā ilāha illallāhul-halīmul-karīm subhānallāhi rabil-a’rshil-a’dhīm al-hamdu lillahi rabil-ā’lamīn asaluka mūjibāti rahmatik wa a’zāima maghfiratik wal-ghanīmata min kulli birr was-salāmata min kulli ithm lā tada’ lī dhamban illā ghafartah wa lā hamman illa farrajtah wa lā hājatan hiya laka ridhan illa qadhaytahā yā arhamar-rāhimīn

Translation: There there no god but Allah the Clement and Wise. There is no god but Allah the High and Mighty. Glory be to Allah, Lord of the Tremendous Throne.  All praise is to Allah, Lord of the worlds.  I ask you (O Allah) everything that leads to your mercy, and your tremendous forgiveness, enrichment in all good, and freedom from all sin.  Do not leave a sin of mine (O Allah), except that you forgive it, nor any concern except that you create for it an opening, nor any need in which there is your good pleasure except that you fulfill it, O Most Merciful!

(Tirmidhi, Hadith # 477)
