It is He who has made the earth subservient to you, so traverse its regions and eat its provisions. To Him you shall all be resurrected. 15 Do ye feel secure that He Who is in heaven will not cause you to be swallowed up by the earth when it shakes (as in an earthquake)? 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 those before them belied (the Messengers of Allah), then how terrible was My denial (punishment)? 18 Did they not see the birds above them, stretching out, and flapping their wings. No one keeps them up in the sky except the Beneficent God. He certainly watches over all things. 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 Or who is this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 21 What, is he who walks prone upon his face better guided than he who walks upright on a straight path? 22 Say: “He it is Who has brought you into being, and has given you hearing and sight, and has given you hearts to think and understand. How seldom do you give thanks!” 23 Say: "It is He Who has created you from the earth, and to Him shall you be gathered (in the Hereafter)." 24 And they say: When shall this threat be (executed) if you are truthful? 25 Say: The knowledge is with Allah only, and I am but a plain warner; 26 At length, when they see it close at hand, grieved will be the faces of the Unbelievers, and it will be said (to them): "This is (the promise fulfilled), which ye were calling for!" 27 Say to them: “Did you ever consider: whether Allah destroys me and those that are with me, or shows mercy to us, who can protect the unbelievers from a grievous chastisement?” 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: "See ye?- If your stream be some morning lost (in the underground earth), who then can supply you with clear-flowing water?" 30
