Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe? 30 And We set in the earth firm mountains lest it should shake with them, and We set in it ravines to serve as ways, that haply so they may be guided; 31 We established the heaven as a well protected roof, yet they still turn away from its signs. 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 And We did not grant to any man before you eternity [on earth]; so if you die - would they be eternal? 34 Every human being is bound to taste death; and We test you [all] through the bad and the good [things of life] by way of trial: and unto Us you all must return. 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 a creature of haste. Soon I will show you My signs, but do not ask Me to hasten them. 37 And they say: When will this threat come to pass if you are truthful? 38 If those who disbelieved but knew the time when they will not be able to drive off the fire from their faces and from their backs, and they will not be helped! 39 Nay, it (the Fire or the Day of Resurrection) will come upon them all of a sudden and will perplex them, and they will have no power to avert it, nor will they get respite. 40 Before you, other Messengers were mocked, but the mockers were encompassed by the very thing they mocked. 41
