It is He who made the earth submissive to you; therefore walk in its tracts, and eat of His provision; to Him is the Uprising. 15 Do you feel secure that He who is in heaven will not cause the earth to sink beneath you and then begin to quake? 16 Do you feel secure that the One in heaven will not send against you a whirlwind to pelt you with stones, so that you will know how [true] My warning was? 17 And verily those before them denied, then (see) the manner of My wrath (with them)! 18 Do they not see the birds above them flying wings spread out or folded? Nothing holds them aloft but God. All things are within His purview. 19 Do you have any armies who will help you against the Beneficent God? The disbelievers are certainly deceived (by satan). 20 Or who is it that will give you sustenance if He should withhold His sustenance? Nay! they persist in disdain and aversion. 21 Then is one who walks fallen on his face better guided or one who walks erect on a straight path? 22 Say: He it is Who brought you into being and made for you the ears and the eyes and the hearts: little is it that you give thanks. 23 Say, “It is He Who has spread you out in the earth, and towards Him you will be raised.” 24 And they say: When shall this threat be (executed) if you are truthful? 25 Say, "God alone has knowledge of that; and I am only a plain warner." 26 Yet in the end, when they shall see that [fulfilment] close at hand, the faces of those who were bent on denying the truth will be stricken with grief; and they will be told, "This it is that you were [so derisively] calling for!" 27 Say: Have you considered if Allah should destroy me and those with me-- rather He will have mercy on us; yet who will protect the unbelievers from a painful punishment? 28 Say: "He is the Most Beneficent (Allah), in Him we believe, and in Him we put our trust. So you will come to know who is it that is in manifest error." 29 Say to them: “Did you even consider: if all the water that you have (in the wells) were to sink down into the depths of the earth, who will produce for you clear, flowing water?” 30
