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 the One in the heavens will not cause you to sink into the earth when it is violently shaking? 16 Do you feel secure that the One in the heavens will not strike you with a sandstorm? You will soon know, with the coming of the torment, how serious Our warning was. 17 And already had those before them denied, and how [terrible] was My reproach. 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 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 But then, is he that goes along with his face close to the ground better guided than he that walks upright on a straight way? 22 Say: 'It is He who produced you, and appointed for you hearing and sight and hearts; little thanks you show!' 23 Say: “Allah it is Who multiplied you in the earth and to Him you will be mustered.” 24 And they say: When (will) this promise (be fulfilled), if ye are truthful? 25 Say thou, [O Prophet:] "Knowledge thereof rests with God alone; and I am only a plain warner." 26 When they realise it has come upon them, distraught will be the faces of unbelievers. They will be told: "This is what you asked for." 27 Say thou: bethink ye if Allah destroy me and those with me; or have mercy on us, who will protect the infidels from a torment afflictive? 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
