(He hath made it) Straight (and Clear) in order that He may warn (the godless) of a terrible Punishment from Him, and that He may give Glad Tidings to the Believers who work righteous deeds, that they shall have a goodly Reward,
（この啓典の内容を）正しく真直になされ，かれの御許からの痛烈な処罰を警告され，また正しい行いをする信者は，善い報奨を得るとの吉報を伝えられた。
