Surah Al-Kahf

(All) praise is due to Allah, Who revealed the Book to His servant and did not make in it any crookedness.

Rightly directing, that he might give warning of severe punishment from Him and give good news to the believers who do good that they shall have a goodly reward,

Staying in it for ever;

And warn those who say: Allah has taken a son.

They have no knowledge of it, nor had their fathers; a grievous word it is that comes out of their mouths; they speak nothing but a lie.
