It is He who made the earth tame for you - so walk among its slopes and eat of His provision - and to Him is the resurrection. 15 Can you ever feel secure that He who is in heaven will not cause the earth to swallow you up when, lo and behold, it begins to quake? 16 Do you feel secure that He Who is in the heaven will not let loose upon you a storm of stones? Then shall you know what My warning is like! 17 And assuredly those before them belied; then what wise hath been My wrath! 18 Have they not seen birds above them spreading and closing their wings, with none holding them except the Merciful One? He oversees everything. 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 Who shall provide for you if He withholds His sustenance? Nay; but they persist in rebellion and aversion. 21 Who is better guided: he who walks grovelling on his face, or he who walks upright on a Straight Path? 22 Proclaim (O dear Prophet Mohammed – peace and blessings be upon him), “It is He Who created you, and made ears and eyes and hearts for you; very little thanks do you offer!” 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 They say: “If you are truthful, tell us when will this promise (of the Hereafter) be fulfilled?” 25 Say (O Muhammad SAW): "The knowledge (of its exact time) is with Allah only, and I am only a plain 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: "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 Beneficent (Allah), in Him we believe, and in Him we put our trust. So you will come to know who is it that is in manifest error." 29 Say [unto those who deny the truth]: "What do you think? If of a sudden all your water were to vanish underground, who [but God] could provide you with water from [new] unsullied springs?" 30
