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 Have ye taken security from Him Who is in the heaven that He will not cause the earth to swallow you when lo! it is convulsed? 16 Or are ye secure that He Who is in the heaven will not send against you a whirlwind? Anon ye shall know what wise hath been My warning. 17 And certainly those before them rejected (the truth), then how was My disapproval. 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 Or which army do you have that will help you against the Most Gracious? The disbelievers are in nothing except an illusion. 20 Who is he that can provide for you if He should withhold His provision? Nay, but they continue to be in pride, and (they) flee (from the truth). 21 Is he who walks grovelling upon his face better guided, or he who walks upright upon a straight path? 22 Say it is He Who has created you, and endowed you with hearing (ears), seeing (eyes), and hearts. Little thanks you give. 23 Say: 'It is He who scattered you in the earth, and unto Him you shall be mustered.' 24 They say: "When will this promise (i.e. the Day of Resurrection) come to pass? if you are telling the truth." 25 Say: “Allah alone knows about that; and I am no more than a plain warner.” 26 When they will see it near at hand, the faces of all those who had denied it will be distraught, and then they will be told: “This is the doom which you used to ask for.” 27 Say: Have you considered if Allah should destroy me and those with me-- rather He will have mercy on us; yet who will protect the unbelievers from a painful punishment? 28 Say, "He is the Most Gracious: we believe in Him and we put our trust in Him. You will soon come to know who is in evident error." 29 Say: 'What think you? If in the morning your water should have vanished into the earth, then who would bring you running water?' 30
