(26:186) You are but a man like ourselves, and indeed, we think you are among the liars. (26:187) So cause to fall upon us fragments of the sky, if you should be of the truthful." (26:188) He said, "My Lord is most knowing of what you do." (26:189) And they denied him, so the punishment of the day of the black cloud seized them. Indeed, it was the punishment of a terrible day. (26:190) Indeed in that is a sign, but most of them were not to be believers. (26:191) And indeed, your Lord - He is the Exalted in Might, the Merciful. (26:192) And indeed, the Qur`an is the revelation of the Lord of the worlds.
