He it is who has made the earth easy to live upon: go about, then, in all its regions, and partake the sustenance which He provides: but [always bear in mind that] unto Him you shall be resurrected. 15 Do you feel secure that He Who is in the heaven will not cause the earth to cave in with you, and then suddenly it will begin to rock violently? 16 Or do ye feel secure that He Who is in Heaven will not send against you a violent tornado (with showers of stones), so that ye shall know how (terrible) was My warning? 17 But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? 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 Do you have any armies who will help you against the Beneficent God? The disbelievers are certainly deceived (by satan). 20 Or who is this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 21 Is he who walks without seeing on his face, more rightly guided, or he who (sees and) walks on a Straight Way (i.e. Islamic Monotheism). 22 Say: 'It is He who produced you, and appointed for you hearing and sight and hearts; little thanks you show!' 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 But they [only] ask, "When is this promise to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 25 Say, "The knowledge is only with Allah, and I am only a clear warner." 26 But when they see it nigh, the faces of those who disbelieve will be awry, and it will be said (unto them): This is that for which ye used to call. 27 Say: 'What think you? If God destroys me and those with me, or has mercy on us, then who will protect the unbelievers from a painful chastisement?' 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: "See ye?- If your stream be some morning lost (in the underground earth), who then can supply you with clear-flowing water?" 30
