As for those whose fate is disbelief, whether you warn them or do not warn them – it is all one for them; they will not believe. (Because their hearts are sealed – see next verse).

Or like a rainstorm from the sky, in which are darkness, thunder and lightning; they thrust their fingers in their ears due to the thunderclaps, fearing death; and Allah has the disbelievers encompassed.

And if you are unable to bring forth (one chapter) – and We declare that you can never bring one – then fear the fire (of hell), the fuel of which is men and stones; kept ready for the disbelievers.

Indeed Allah does not, for the sake of explanation, shy to illustrate an example of anything, whether it is of a gnat or something further (inferior) than it; so the believers know it is the Truth from their Lord; as for the disbelievers, they say, “What does Allah intend by such an example?” He misleads many thereby, and He guides many thereby; and with it He misleads only those who are rebellious.

And (remember) when We ordered the angels to prostrate before Adam, so they all prostrated, except Iblis (Satan – devil); he refused and was proud – and became a disbeliever.
