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 the One in the heavens will not cause you to sink into the earth when it is violently shaking? 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 assuredly those before them belied; then what wise hath been My wrath! 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 this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 21 Can one who walks with his head hanging down be better guided that one who walks with his head upright? 22 Say it is He Who has created you, and endowed you with hearing (ears), seeing (eyes), and hearts. Little thanks you give. 23 Say: “Allah it is Who multiplied you in the earth and to Him you will be mustered.” 24 They ask, "When will this promise be fulfilled, if you are truthful?" 25 Say: 'The knowledge is with God; I am only a clear warner.' 26 Then, when they see it drawing near, the faces of the unbelievers will be blackened, and it is said: 'This is what you were promised' 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 to them: “He is Merciful, and it is in Him that we believe, and it is in Him that we put all our trust. Soon will you know who is in manifest 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
