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 sky a roof withheld (from them). Yet they turn away from its portents. 32 And He it is Who created the night and the day and the sun and the moon; all (orbs) travel along swiftly in their celestial spheres. 33 We made no mortal before you immortal. Will they become immortal after you die? 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 (Muhammad), whenever the unbelievers see you, they think that you deserve nothing more than to be mocked. They say, "Is it he, (Muhammad), who speaks against your gods?" But they themselves have no faith at all in the Beneficent God. 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 occur, if you are truthful? 38 If the unbelievers only knew when they will be unable to shield either their faces or their backs from the Fire; when they will not be helped! 39 That will suddenly come upon them and stupefy them. They shall not be able to ward it off, nor shall they be granted any respite. 40 Many apostles have been scoffed before you; but they who scoffed were themselves caught by what they had ridiculed. 41
