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 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 And We did not ordain abiding for any mortal before you. What! Then if you die, will they abide? 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 But when the unbelievers see you they make fun of you (and say): "Is this the one who mentions your gods (deridingly)?" Yet in Ar-Rahman they disbelieve! 36 Man was created of haste, surely I shall show you My signs, so ask Me not to hasten. 37 And they say, “When will this promise occur, if you are truthful? 38 If they but knew - they who are bent on denying the truth - [that there will come] a time when they will not be able to ward off the fire from their faces, nor from their backs, and will not find any succour! 39 Nay, it (the Fire or the Day of Resurrection) will come upon them all of a sudden and will perplex them, and they will have no power to avert it, nor will they get respite. 40 Before you, other Messengers were mocked, but the mockers were encompassed by the very thing they mocked. 41
