Translation
O Most High! O All-great! O All-forgiving! O All-merciful! You are the All-great Lord like Whom there is nothing, and He is the All-hearing, the All-aware. This is a month that You have glorified, ennobled, honored, and preferred to the other months. It is the month that You imposed upon me to observe fasting in it. It is the month of Ramadan during which You revealed the Qur'an as guidance for people, clear proofs on true guidance, and distinction (between the right and the wrong). You decided the Grand Night to be in it and You have decided it to be more favorable that one thousand months.
