He it is Who made the earth smooth for you, therefore go about in the spacious sides thereof, and eat of His sustenance, and to Him is the return after death. 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 do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning? 17 Those who lived before them had also rejected Our warning, and how terrible was Our retribution! 18 Behold they not the birds above them, outstretching their wings and they also withdraw them? Naught holdeth them except the Compassionate. Verily He is of everything Beholder. 19 Or which army do you have that will help you against the Most Gracious? The disbelievers are in nothing except an illusion. 20 Who shall provide for you if He withholds His sustenance? Nay; but they persist in rebellion and aversion. 21 Will he find the way who grovels flat on his face, or he who walks straight on the right 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: 'It was He who created you, dispersing you in the earth, and to Him you shall be gathered' 24 And they say: when will this promise be fulfilled, if ye say sooth? 25 Say, "The knowledge is only with Allah, and I am only a clear warner." 26 But when they see it approaching, the faces of those who disbelieve will be distressed, and it will be said, "This is that for which you used to call." 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 thou: He is the Compassionate; in Him we have believed, and in Him we have put our trust. And anon ye will know who it is that is in error manifest. 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
