It is He who has made the earth subservient to you, so traverse its regions and eat its provisions. To Him you shall all be resurrected. 15 Are ye secure that He who is in the heaven will not sink the earth with you and then it should quake? 16 Or have you become unafraid of the One Who controls the heavens, that He will not send a torrent of stones upon you? So now you will realise, how My warning turned out! 17 And certainly those before them rejected (the truth), then how was My disapproval. 18 Have they, then, never beheld the birds above them, spreading their wings and drawing them in? None but the Most Gracious upholds them: for, verily, He keeps all things in His sight. 19 Or who is it that could be an army for you to aid you other than the Most Merciful? The disbelievers are not but in delusion. 20 Or who is it that will give you sustenance if He should withhold His sustenance? Nay! they persist in disdain and aversion. 21 So is one who walks inverted upon his face more rightly guided, or one who walks upright on the Straight Path? 22 Say: 'It is He who produced you, and appointed for you hearing and sight and hearts; little thanks you show!' 23 Say, “It is He Who has spread you out in the earth, and towards Him you will be raised.” 24 But they say: "When will this promise come to pass, if what you say is true?" 25 Say (O Muhammad SAW): "The knowledge (of its exact time) is with Allah only, and I am only a plain warner." 26 But when they see it drawing near, the faces of those who deny the truth will turn gloomy and they will be told, "This is what you were calling for." 27 Say thou: bethink ye if Allah destroy me and those with me; or have mercy on us, who will protect the infidels from a torment afflictive? 28 Say: 'He is the Merciful. In Him we believe and in Him we put all our trust. Indeed, you shall soon know who is in clear error' 29 Say, "Have you considered: if your water was to become sunken [into the earth], then who could bring you flowing water?" 30
