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 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 Do you feel secure that the One in heaven will not send against you a whirlwind to pelt you with stones, so that you will know how [true] My warning was? 17 And already had those before them denied, and how [terrible] was My reproach. 18 Do they not see the birds above them, spreading out their wings and folding them in? None upholds them except the Most Beneficent (Allah). Verily, He is the All-Seer of 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 shall provide for you if He withholds His sustenance? Nay; but they persist in rebellion and aversion. 21 Is he, then, who goeth about grovelling upon his face better directed, or he who walketh evenly on a straight path? 22 Say: "It is He who raised you and gave you ears and eyes and hearts. How little are the thanks you offer!" 23 Say: He it is Who multiplieth you in the earth, and unto Whom ye will be gathered. 24 And they say: when will this promise be fulfilled, if ye say sooth? 25 Say: The knowledge is with Allah only, and I am but a plain warner; 26 But when they will behold it proximating sad will be the countenances of those who disbelieve, and it will be said: this is that which ye have been calling for. 27 Say (O Muhammad): Have ye thought: Whether Allah causeth me (Muhammad) and those with me to perish or hath mercy on us, still, who will protect the disbelievers from a painful doom? 28 Say, "He is the Most Gracious: we believe in Him and we put our trust in Him. You will soon come to know who is in evident 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
