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 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 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 Those who came before them also gave the lie (to the Messengers): then how awesome was My chastisement! 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 he that will be an army unto you to help you instead of the Beneficent? The disbelievers are in naught but illusion. 20 Who is he that can provide for you if He should withhold His provision? Nay, but they continue to be in pride, and (they) flee (from the truth). 21 Is he who walks grovelling upon his face better guided, or he who walks upright upon a straight path? 22 (Muhammad), say, "It is God who has brought you into being and made ears, eyes, and hearts for you, but you give very little thanks". 23 Say thou: He it is Who hath spread you over the earth, and unto Him ye shall be gathered. 24 They ask, "When will this promise be fulfilled, if you are truthful?" 25 Say, "God knows best. I am only one who gives warning". 26 When they will see it near at hand, the faces of all those who had denied it will be distraught, and then they will be told: “This is the doom which you used to ask for.” 27 Say: "Just think: If God destroys me and those with me, or is benevolent to us, who will then protect the unbelievers from a painful doom?" 28 Say: 'He is the All-merciful. We believe in Him, and in Him we put all our trust. Assuredly, you will soon, know who is in manifest error. 29 Say: "Just think: If your water were to dry up in the morning who will bring you water from a fresh, flowing stream?" 30
