Have not the unbelievers then beheld that the heavens and the earth were a mass all sewn up, and then We unstitched them and of water fashioned every living thing? Will they not believe? 30 And We have placed in the earth firm mountains lest it should move away with them, and We placed therein passages for paths, that haply they may be guided. 31 And We made the sky a protected ceiling, but they, from its signs, are turning away. 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 appointed immortality for no mortal before thee. What! if thou diest, can they be immortal! 34 Every living being must taste death; and We test you with harm and with good – a trial; and to Us only you have to return. 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 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 (come to pass), if you are truthful." 38 Had those who disbelieve but known (of the time) when they shall not be able to ward off the fire from their faces nor from their backs, nor 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 already were messengers ridiculed before you, but those who mocked them were enveloped by what they used to ridicule. 41
