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 have placed in the earth firm hills lest it quake with them, and We have placed therein ravines as roads that haply they may find their way. 31 We established the heaven as a well protected roof, yet they still turn away from its signs. 32 And He it is Who hath created the night and the day, and the sun and the moon, each in an orb floating. 33 We granted not to any man before thee permanent life (here): if then thou shouldst die, would they live permanently? 34 Every soul shall taste of death; and We try you with evil and good for a testing, then unto Us you shall be returned. 35 And when those who disbelieve see you, [O Muhammad], they take you not except in ridicule, [saying], "Is this the one who insults your gods?" And they are, at the mention of the Most Merciful, disbelievers. 36 Man is a creature of haste; [but in time] I shall make obvious to you [the truth of] My messages: do not, then, ask Me to hasten [it]! 37 And they say, “When will this promise occur, if you are truthful? 38 If the unbelievers but knew when that they shall not ward off the Fire from their faces nor from their backs, neither shall they 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 And indeed, [O Muhammad, even] before thy time have [God's] apostles been derided - but those who scoffed at them were [in the end] overwhelmed by the very thing which they had been wont to deride. 41
