It is He who made the earth subservient to you that you may travel all around it, and eat of things He has provided; and to Him will be your resurrection. 15 Have you become unafraid of the One Who controls the heavens, that He will not cause you to sink into the earth when it trembles? 16 Or have you become so unafraid that He who is in Heaven will not send a violent wind to shower stones at you? Then you will know the import of My commination! 17 Those who lived before them had also rejected Our warning, and how terrible was Our retribution! 18 Do they not observe the birds above them, spreading their wings and folding them? None, except the Merciful holds them. Surely, He sees all things. 19 Nay, who is there that can help you, (even as) an army, besides (Allah) Most Merciful? In nothing but delusion are the Unbelievers. 20 Or who is this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 21 Can one who walks with his head hanging down be better guided that one who walks with his head upright? 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 dispersed you all over the earth, and to Him you will be gathered." 24 They say: "When will this promise (i.e. the Day of Resurrection) come to pass? if you are telling the truth." 25 Say: 'The knowledge (of that) is with Allah; I am only a clear warner' 26 So when they will see it close, the faces of the disbelievers will become ghastly, and it will be declared, “This is what you were demanding.” 27 Say: 'What do you think, if Allah destroys me and those with me, or has mercy upon us, who then will protect the unbelievers from the painful punishment' 28 Say, "He is the Beneficent One in whom we have faith and trust. You will soon know who is in manifest error". 29 Say: Have ye thought: If (all) your water were to disappear into the earth, who then could bring you gushing water? 30
