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 And We have placed on the earth firm mountains, lest it should shake with them, and We placed therein broad highways for them to pass through, that they may be guided. 31 And We have made the heaven a roof, safe, and from the signs thereof they are averters. 32 It is He Who created the Night and the Day, and the sun and the moon: all (the celestial bodies) swim along, each in its rounded course. 33 We appointed immortality for no mortal before thee. What! if thou diest, can they be immortal! 34 Every soul must taste of death and We try you by evil and good by way of probation; and to Us you shall be brought back. 35 And when those who disbelieve behold thee they only take thee up for mockery: is this he who mentioneth your gods? while in the mention of the compassionate they are themselves blasphemers. 36 Man is made of haste. I shall show you My portents, but ask Me not to hasten. 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 shall come upon them suddenly, dumbfounding them, and they shall not be able to repel it, nor shall they be respited. 40 And already were messengers ridiculed before you, but those who mocked them were enveloped by what they used to ridicule. 41
