It is He who has made the earth submissive to you. Walk about in its land and eat of His provision. To Him is the Resurrection. 15 Do you feel secure that He, Who is over the heaven (Allah), will not cause the earth to sink with you, then behold it shakes (as in an earthquake)? 16 Do you feel secure that the One in the heavens will not strike you with a sandstorm? You will soon know, with the coming of the torment, how serious Our warning was. 17 And certainly those before them rejected (the truth), then how was My disapproval. 18 Do they not see the birds above them flying wings spread out or folded? Nothing holds them aloft but God. All things are within His purview. 19 Or who is it that will be a host for you to assist you besides the Beneficent Allah? The unbelievers are only in deception. 20 Or, who is it that shall provide for you if He withholds His provision? Yet they persist in arrogance and aversion. 21 But then, is he that goes along with his face close to the ground better guided than he that walks upright on a straight way? 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: He it is Who multiplied you in the earth and to Him you shall be gathered. 24 They ask, "When will this promise be fulfilled, if you are truthful?" 25 Say: “Allah alone knows about that; and I am no more than a plain warner.” 26 But when they will see it (the torment on the Day of Resurrection) approaching, the faces of those who disbelieve will be different (black, sad, and in grieve), and it will be said (to them): "This is (the promise) which you were 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 Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that is in clear 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
