It is He who has made the earth submissive to you. Walk about in its land and eat of His provision. To Him is the Resurrection. 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 Those before them had also denied. And how was My punishment then! 18 Do they not see the birds above them with wings outspread and [sometimes] folded in? None holds them [aloft] except the Most Merciful. Indeed He is, of all things, Seeing. 19 Or who is it that could be an army for you to aid you other than the Most Merciful? The disbelievers are not but in delusion. 20 Is there anyone who will provide you with sustenance if God were to deny you sustenance? In fact, they obstinately persist in their transgression and hatred. 21 What, is he who walks prone upon his face better guided than he who walks upright on a straight path? 22 Say: "It is He who raised you and gave you ears and eyes and hearts. How little are the thanks you offer!" 23 Say: 'It is He who scattered you in the earth, and unto Him you shall be mustered.' 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 (of that) is with Allah; I am only a clear 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 [O Prophet]: "What do you think? Whether God destroys me and those who follow me, or graces us with His mercy - is there anyone that could protect [you] deniers of the truth from grievous suffering [in the life to come]?" 28 Say to them: “He is Merciful, and it is in Him that we believe, and it is in Him that we put all our trust. Soon will you know who is in manifest 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
