Aforetime, for a guidance to mankind; and hath revealed the Criterion (of right and wrong). Lo! those who disbelieve the revelations of Allah, theirs will be a heavy doom. Allah is Mighty, Able to Requite (the wrong).
Before, as guidance for the people. And He revealed the Criterion [i.e., the Qur’ān]. Indeed, those who disbelieve in the verses of Allah will have a severe punishment, and Allah is Exalted in Might, the Owner of Retribution.1
