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 And We have made the heaven a roof, safe and well guarded. Yet they turn away from its signs (i.e. sun, moon, winds, clouds, etc.). 32 And it is He Who created the night and the day, and the sun and the moon; each one floats in an orbit. 33 We made no mortal before you immortal. Will they become immortal after you die? 34 Every soul will taste death. And We test you with evil and with good as trial; and to Us you will be returned. 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 was created of haste, surely I shall show you My signs, so ask Me not to hasten. 37 But they [who reject My messages are wont to] ask, "When is that promise [of God's judgment] to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 38 If only the disbelievers realised the time when they will not be able to stop the fire from their faces and from their backs – and nor are they to be helped. 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
