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 Have you become unafraid of the One Who controls the heavens, that He will not cause you to sink into the earth when it trembles? 16 Or do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning? 17 And already had those before them denied, and how [terrible] was My reproach. 18 Behold they not the birds above them, outstretching their wings and they also withdraw them? Naught holdeth them except the Compassionate. Verily He is of everything Beholder. 19 Or who is this that shall be a host for you to help you, apart from the All-merciful? The unbelievers are only in delusion. 20 Or who is it that could provide for you if He withheld His provision? But they have persisted in insolence 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: “He it is Who has brought you into being, and has given you hearing and sight, and has given you hearts to think and understand. How seldom do you give thanks!” 23 Say: "It is He who dispersed you all over the earth, and to Him you will be gathered." 24 They say: "When will this promise (i.e. the Day of Resurrection) come to pass? if you are telling the truth." 25 Say: The knowledge is with Allah only, and I am but a plain warner; 26 But when they see it nigh, the faces of those who disbelieve will be awry, and it will be said (unto them): This is that for which ye used to call. 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 Proclaim, “He only is the Most Gracious – we have accepted faith in Him and have relied only upon Him; so you will now realise who is in open error.” 29 Say thou: bethink ye, were your water to be sunk away, who then could bring you water welling-up? 30
