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 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 certainly those before them rejected (the truth), then how was My disapproval. 18 Do they not see the birds above them spreading and closing their wings? None save the Merciful sustains them. Surely, He observes all things. 19 Who is there to defend you like an army, besides the Lord of Mercy? Those who deny the truth are in deception. 20 Or who is it that could provide for you if He withheld His provision? But they have persisted in insolence 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 made you grow), and made for you the faculties of hearing, seeing, feeling and understanding: little thanks it is ye give. 23 Say thou: He it is Who hath spread you over the earth, and unto Him ye shall be gathered. 24 But they [only] ask, "When is this promise to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 25 Say thou: the knowledge is only with Allah, and I am but a warner manifest. 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 (Muhammad), say, "Have you not considered that regardless whether God forgives me and my followers or grants us mercy, but who will protect the disbelievers from a painful torment? 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, "Have you not thought that if your water was to dry up, who would bring you water from the spring?" 30
