He it is Who hath made the earth subservient unto you, so Walk in the paths thereof and eat of His providence. And unto Him will be the resurrection (of the dead). 15 Are you secure of those in the heaven that He should not make the earth to swallow you up? Then lo! it shall be in a state of commotion. 16 Do you feel secure that He who is in heaven will not loose against you a squall of pebbles, then you shall know how My warning is? 17 And indeed, [many of] those who lived aforetime did give the lie [to My warnings]: and how awesome was My rejection [of them]! 18 Have they not regarded the birds above them spreading their wings, and closing them? Naught holds them but the All-merciful. Surely He sees everything. 19 Who is there to defend you like an army, besides the Lord of Mercy? Those who deny the truth are in deception. 20 Or who is it that will give you sustenance if He should withhold His sustenance? Nay! they persist in disdain and aversion. 21 Is then one who walks headlong, with his face grovelling, better guided,- or one who walks evenly on a Straight Way? 22 SAY: "[God is] He who has brought you [all] into being, and has endowed you with hearing, and sight, and hearts: [yet] how seldom are you grateful!" 23 Say: "It is He who has multiplied you on earth; and it is unto Him that you shall be gathered [on resurrection]." 24 They ask, "When will this promise be fulfilled, if you are truthful?" 25 Say: "As to the knowledge of the time, it is with Allah alone: I am (sent) only to warn plainly in public." 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: "Just think: If God destroys me and those with me, or is benevolent to us, who will then protect the unbelievers from a painful doom?" 28 Say: 'He is the All-merciful. We believe in Him, and in Him we put all our trust. Assuredly, you will soon, 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
