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 Can you ever feel secure that He who is in heaven will not cause the earth to swallow you up when, lo and behold, it begins to quake? 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 verily those before them denied, then (see) the manner of My wrath (with them)! 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 such that will give you sustenance if Allah stops His sustenance? In fact they persist in rebellion and hatred. 21 What, is he who walks, falling upon his face, more guided than he who walks upright on a Straight Path! 22 Say: "It is He Who has created you (and made you grow), and made for you the faculties of hearing, seeing, feeling and understanding: little thanks it is ye give. 23 Say: He it is Who multiplieth you in the earth, and unto Whom ye 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, "God knows best. I am only one who gives warning". 26 Then, when they see it nigh at hand, the faces of the unbelievers will be vexed, and it will be said, 'This is what you were promised.' 27 Say (O Muhammad SAW): "Tell me! If Allah destroys me, and those with me, or He bestows His Mercy on us, - who can save the disbelievers from a painful torment?" 28 Say: 'He is the All-merciful. We believe in Him, and in Him we put all our trust. Assuredly, you will soon, know who is in manifest error. 29 Say, "Have you considered: if your water was to become sunken [into the earth], then who could bring you flowing water?" 30
