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 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 indeed those before them belied (the Messengers of Allah), then how terrible was My denial (punishment)? 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 Who is there to defend you like an army, besides the Lord of Mercy? Those who deny the truth are in deception. 20 Or who is he that will provide for you if He should withhold His providence? Nay, but they are set in pride and frowardness. 21 So is one who walks inverted upon his face more rightly guided, or one who walks upright on the Straight Path? 22 Say, "It is He who has produced you and made for you hearing and vision and hearts; little are you grateful." 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, "The knowledge is only with Allah, and 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 dear Prophet Mohammed – peace and blessings be upon him), “What is your opinion –Allah may either destroy me and those with me, or have mercy on us – so who is such that will protect the disbelievers from the painful punishment?” 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
