It is He who has made the earth subservient to you. You walk through its vast valleys and eat of its sustenance. Before Him you will 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 can you ever feel secure that He who is in heaven will not let loose against you a deadly stormwind, whereupon you would come to know how [true] My warning was? 17 And indeed, [many of] those who lived aforetime did give the lie [to My warnings]: and how awesome was My rejection [of them]! 18 Did they not see the birds above them, stretching out, and flapping their wings. No one keeps them up in the sky except the Beneficent God. He certainly watches over all things. 19 Or, who is it that shall be your host to help you, other than the Merciful? Indeed, the unbelievers are only deluded. 20 Or who is it that will give you sustenance if He should withhold His sustenance? Nay! they persist in disdain and aversion. 21 But then, is he that goes along with his face close to the ground better guided than he that walks upright on a straight way? 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 scattered you on the earth; and it is to Him that you shall all be gathered [on the Day of Resurrection]. 24 They ask: When will this promise be (fulfilled)? - If ye are telling the truth. 25 Say thou, [O Prophet:] "Knowledge thereof rests with God alone; and I am only a plain warner." 26 But when they see it nigh, the faces of those who disbelieve will be awry, and it will be said (unto them): This is that for which ye used to call. 27 (Muhammad), say, "Have you not considered that regardless whether God forgives me and my followers or grants us mercy, but who will protect the disbelievers from a painful torment? 28 Say: 'He is the Merciful. In Him we believe and in Him we put all our trust. Indeed, you shall soon know who is in clear error' 29 Say: Have you considered if your water should go down, who is it then that will bring you flowing water? 30
