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 We placed firm mountains on earth lest it would shake them away. We made wide roads for them so that they might have the right guidance. 31 We made the sky above them as a well-guarded ceiling, but they have neglected the evidence (of Our existence) therein. 32 and [fail to see that] it is He who has created the night and the day and the sun and the moon - all of them floating through space! 33 (O Muhammad), We did not grant everlasting life to any human being even before you. If you were to die, will they live for ever? 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 When those who deny the truth see you, they laugh at you, saying, "Is this the one who talks of your deities?" Yet it is they who deny all mention of the Gracious One. 36 The human being is created hasty. Tell them, "Do not be hasty, for God will soon show you the evidence of His existence". 37 And they say: When will this promise (be fulfilled), if ye 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, but it will come upon them unawares so that it will stupefy them, and they will be unable to repel it, neither will they be reprieved. 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
