Surah Al-Kahf

Praise be to Allah, Who hath sent to His Servant the Book, and hath allowed therein no Crookedness:

(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,

Wherein they shall remain for ever:

Further, that He may warn those (also) who say, "Allah hath begotten a son":

No knowledge have they of such a thing, nor had their fathers. It is a grievous thing that issues from their mouths as a saying what they say is nothing but falsehood!
