It is He who has made the earth subservient to you, so traverse its regions and eat its provisions. To Him you shall all be resurrected. 15 Do you feel secure that He who is in heaven will not cause the earth to swallow you, the while it rocks? 16 Or do you feel secure that He who [holds authority] in the heaven would not send against you a storm of stones? Then you would know how [severe] was My warning. 17 And verily those before them denied, then (see) the manner of My wrath (with them)! 18 Do they not observe the birds above them, spreading their wings and folding them in? None can uphold them except (Allah) Most Gracious: Truly (Allah) Most Gracious: Truly it is He that watches over all things. 19 Who is he that can be an army unto you and succour you, beside the Compassionate! The infidels are but in delusion. 20 Or is there any that could provide you with sustenance if He should withhold His provision [from you]? Nay, but they [who are bent on denying the truth] stubbornly persist in their disdain [of God's messages] and in their headlong flight [from Him]! 21 What, is he who walks prone upon his face better guided than he who walks upright on a straight path? 22 Say: He it is Who brought you into being and made for you the ears and the eyes and the hearts: little is it that you give thanks. 23 Say: "It is He Who has created you from the earth, and to Him shall you be gathered (in the Hereafter)." 24 They say, "When will this torment take place if what you say is true?" 25 Say thou: the knowledge is only with Allah, and I am but a warner manifest. 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: '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. In Him we believe and in Him we put our trust. And ye will soon know who it is that is in error manifest. 29 Say, "Have you considered if your water were to sink into the ground, who could then bring you flowing water?" 30
