He it is who has made the earth easy to live upon: go about, then, in all its regions, and partake the sustenance which He provides: but [always bear in mind that] unto Him you shall be resurrected. 15 Do you feel secure that He who [holds authority] in the heaven would not cause the earth to swallow you and suddenly it would sway? 16 Or do you feel secure that He who [holds authority] in the heaven would not send against you a storm of stones? Then you would know how [severe] was My warning. 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 regarded the birds above them spreading their wings, and closing them? Naught holds them but the All-merciful. Surely He sees everything. 19 Who is he besides the Most Beneficent that can be an army to you to help you? The disbelievers are in nothing but delusion. 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 Say: He it is Who brought you into being and made for you the ears and the eyes and the hearts: little is it that you give thanks. 23 Say: "It is He who has multiplied you on earth; and it is unto Him that you shall be gathered [on resurrection]." 24 And they say: When shall this threat be (executed) if you are truthful? 25 Proclaim, “Surely Allah has its knowledge; and I am only a Herald of plain warning.” 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 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 thou: bethink ye, were your water to be sunk away, who then could bring you water welling-up? 30
