He it is Who made the earth subservient to you. So traverse in its tracks and partake of the sustenance He has provided. To Him will you be resurrected. 15 Can you ever feel secure that He who is in heaven will not cause the earth to swallow you up when, lo and behold, it begins to quake? 16 Or have ye taken security from Him Who is in the heaven that He will not let loose on you a hurricane? But ye shall know the manner of My warning. 17 And already had those before them denied, and how [terrible] was My reproach. 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 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 he that will provide for you if He should withhold His providence? Nay, but they are set in pride and frowardness. 21 Then is one who walks fallen on his face better guided or one who walks erect on a straight path? 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, "It is God who has settled you on the earth and to Him you will be resurrected". 24 They say: “If you are truthful, tell us when will this promise (of the Hereafter) be fulfilled?” 25 Say: “Allah alone knows about that; and I am no more than 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: 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 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: 'What do you think. If your water should sink into the earth in the morning, who then would bring you running water' 30
