It is He who made the earth subservient to you that you may travel all around it, and eat of things He has provided; and to Him will be your resurrection. 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 are ye secure that He Who is in the heaven will not send against you a whirlwind? Anon ye shall know what wise hath been My warning. 17 Those that were before them also cried lies; then how was My horror! 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 Or who is this that shall be a host for you to help you, apart from the All-merciful? The unbelievers are only in delusion. 20 Or is there any that could provide you with sustenance if He should withhold His provision [from you]? Nay, but they [who are bent on denying the truth] stubbornly persist in their disdain [of God's messages] and in their headlong flight [from Him]! 21 So is one who walks inverted upon his face more rightly guided, or one who walks upright on the Straight 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 is He who has scattered you on the earth; and it is to Him that you shall all be gathered [on the Day of Resurrection]. 24 And they say: When (will) this promise (be fulfilled), if ye are truthful? 25 Say: “Allah alone knows about that; and I am no more than 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: "See ye?- If Allah were to destroy me, and those with me, or if He bestows His Mercy on us,- yet who can deliver the Unbelievers from a grievous Penalty?" 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 (O Muhammad SAW): "Tell me! If (all) your water were to be sunk away, who then can supply you with flowing (spring) water?" 30
