Do not those who disbelieve see that the heavens and the earth were closed up, but We have opened them; and We have made of water everything living, will they not then believe? 30 We set firm mountains upon the earth lest it should shake with them, and We placed therein ravines to be paths so that they might be guided. 31 And we have made the sky a roof withheld (from them). Yet they turn away from its portents. 32 And it is He Who created the night and the day, and the sun and the moon; each one floats in an orbit. 33 We have not assigned to any mortal before thee to live forever; therefore, if thou diest, will they live forever? 34 Every soul must taste of death, and We try you with evil and with good, for ordeal. And unto Us ye will be returned. 35 But [thus it is:] whenever they who are bent on denying the truth consider thee, they make thee but a target of their mockery, [saying to one another,] "Is this the one who speaks [so contemptuously] of your gods?" and yet, it is they themselves who, at [every] mention of the Most Gracious, are wont to deny the truth! 36 Man is made of haste. I shall show you My portents, but ask Me not to hasten. 37 And they say, "When is this promise, if you should be truthful?" 38 Would that the unbelievers knew that no one would protect their faces and backs against the fire, nor they would be helped. 39 That will suddenly come upon them and stupefy them. They shall not be able to ward it off, nor shall they be granted any respite. 40 Messengers indeed were mocked at before thee, but those that scoffed at them were encompassed by that they mocked at. 41
