There is nothing which deserves to be worshipped but You. You are my Rabb (Lord) and I am Your slave. I have wronged myself, but I acknowledge my sin, so forgive me all my sins, You alone can forgive sins; and guide me to the best qualities, You alone can guide to the best of them: and turn me from evil ones, You alone can turn from evil qualities.
