It is He who made the earth subservient to you that you may travel all around it, and eat of things He has provided; and to Him will be your resurrection. 15 Do you feel secure that He who is in the heaven will not cause the earth to swallow you up while it shakes? 16 Or have you become so unafraid that He who is in Heaven will not send a violent wind to shower stones at you? Then you will know the import of My commination! 17 Those who came before them also gave the lie (to the Messengers): then how awesome was My chastisement! 18 Have they not seen the birds above them expanding (their wings) and contracting (them)? What is it that withholds them save the Beneficent Allah? Surely He sees everything. 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 Who shall provide for you if He withholds His sustenance? Nay; but they persist in rebellion and aversion. 21 Can one who walks with his head hanging down be better guided that one who walks with his head upright? 22 Say, "It is He who has produced you and made for you hearing and vision and hearts; little are you grateful." 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 But they say: "When will this promise come to pass, if what you say is true?" 25 Say: "God alone has knowledge. My duty is only to warn you clearly." 26 But when they shall see it nigh, the faces of those who disbelieve shall be sorry, and it shall be said; This is that which you used to call 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 Most Beneficent (Allah), in Him we believe, and in Him we put our trust. So you will come to know who is it that is in manifest error." 29 Say, “What is your opinion – if in the morning all your water were to sink into the earth, then who is such who can bring you water flowing before you?” 30
