He it is Who hath made the earth subservient unto you, so Walk in the paths thereof and eat of His providence. And unto Him will be the resurrection (of the dead). 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 But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? 18 Have they not seen birds above them spreading and closing their wings, with none holding them except the Merciful One? He oversees everything. 19 Or who is it that will be a host for you to assist you besides the Beneficent Allah? The unbelievers are only in deception. 20 Or who is there that can provide you with Sustenance if He were to withhold His provision? Nay, they obstinately persist in insolent impiety and flight (from the Truth). 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 scattered you in the earth, and unto Him you shall be mustered.' 24 And they say: when will this promise be fulfilled, if ye say sooth? 25 Say, "God alone has knowledge of that; and I am only a plain warner." 26 When they realise it has come upon them, distraught will be the faces of unbelievers. They will be told: "This is what you asked 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 to them: “He is Merciful, and it is in Him that we believe, and it is in Him that we put all our trust. Soon will you know who is in manifest error.” 29 Say: "See ye?- If your stream be some morning lost (in the underground earth), who then can supply you with clear-flowing water?" 30
