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 Are you so unafraid that He who is in Heaven will not open up the earth to swallow you, when it will begin to tremble? 16 Or can you ever feel secure that He who is in heaven will not let loose against you a deadly stormwind, whereupon you would come to know how [true] My warning was? 17 And indeed, [many of] those who lived aforetime did give the lie [to My warnings]: and how awesome was My rejection [of them]! 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 Which is your army that will come to your aid against the Merciful Lord? But the unbelievers are in utter delusion. 20 Who shall provide for you if He withholds His sustenance? Nay; but they persist in rebellion and aversion. 21 Then is one who walks fallen on his face better guided or one who walks erect on a straight path? 22 Proclaim (O dear Prophet Mohammed – peace and blessings be upon him), “It is He Who created you, and made ears and eyes and hearts for you; very little thanks do you offer!” 23 Say: He it is Who multiplieth you in the earth, and unto Whom ye will be gathered. 24 They say, "When will this torment take place if what you say is true?" 25 Say: "God alone has knowledge. My duty is only to warn you clearly." 26 So when they will see it close, the faces of the disbelievers will become ghastly, and it will be declared, “This is what you were demanding.” 27 Say: 'What think you? If God destroys me and those with me, or has mercy on us, then who will protect the unbelievers from a painful chastisement?' 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, "Have you considered if your water were to sink into the ground, who could then bring you flowing water?" 30
