It is He who has made the earth subservient to you. You walk through its vast valleys and eat of its sustenance. Before Him you will all be resurrected. 15 Have ye taken security from Him Who is in the heaven that He will not cause the earth to swallow you when lo! it is convulsed? 16 Do you feel secure that He who is in heaven will not loose against you a squall of pebbles, then you shall know how My warning is? 17 And indeed those before them belied (the Messengers of Allah), then how terrible was My denial (punishment)? 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 Nay, who is there that can help you, (even as) an army, besides (Allah) Most Merciful? In nothing but delusion are the Unbelievers. 20 Or who is this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 21 Is he who goeth groping on his face more rightly guided, or he who walketh upright on a straight road? 22 Say: 'It is He who has created you and given to you hearing, sight and hearts but little is it that you thank' 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 They say, 'When shall this promise come to pass, if you speak truly?' 25 Say: "God alone has knowledge. My duty is only to warn you clearly." 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, [O Muhammad], "Have you considered: whether Allah should cause my death and those with me or have mercy upon us, who can protect the disbelievers from a painful punishment?" 28 Say: He is the Beneficent Allah, we believe in Him and on Him do we rely, so you shall come to know who it is that is in clear 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
