ARE, THEN, they who are bent on denying the truth not aware that the heavens and the earth were [once] one single entity, which We then parted asunder? and [that] We made out of water every living thing? Will they not, then, [begin to] 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 heaven a roof, safe, and from the signs thereof they are averters. 32 It is He who created the night and the day, the sun and the moon, each swimming in a sky. 33 And We did not ordain abiding for any mortal before you. What! Then if you die, will they abide? 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 When the unbelievers see you they make you an object of fun, saying: "Is he the one who mentions your gods?" They say so, and yet they reject with disdain the very mention of the Most Compassionate Lord. 36 The human was created of haste. Indeed, I will show you My signs; so do not ask Me to hasten them. 37 Yet they say: "When will the promised threat come to pass, if you speak the truth?" 38 If only the unbelievers could apprehend the moment when they would neither be able to ward off the fire from their faces and their backs, nor help reach them! 39 In fact it will suddenly come upon them, therefore shocking them, and they will not be able to repel it nor will they be given respite. 40 And already were messengers ridiculed before you, but those who mocked them were enveloped by what they used to ridicule. 41
