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 Are you secure of those in the heaven that He should not make the earth to swallow you up? Then lo! it shall be in a state of commotion. 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 But indeed men before them rejected (My warning): then how (terrible) was My rejection (of them)? 18 And did they not see the birds above them, spreading and closing their wings? None except the Most Gracious holds them up; indeed He sees all things. 19 Or who is it that will be a host for you to assist you besides the Beneficent Allah? The unbelievers are only in deception. 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 Is he, then, who goeth about grovelling upon his face better directed, or he who walketh evenly on a straight path? 22 Say: 'It is He who has created you and given to you hearing, sight and hearts but little is it that you thank' 23 Say: "It is He who dispersed you all over the earth, and to Him you will be gathered." 24 And they say: When (will) this promise (be fulfilled), if ye are truthful? 25 Say: “Allah alone knows about that; and I am no more than a plain warner.” 26 When they see the torment approaching, the faces of the disbelievers will blacken and they will be told, "This is what you wanted to (experience)". 27 Say to them: “Did you ever consider: whether Allah destroys me and those that are with me, or shows mercy to us, who can protect the unbelievers from a grievous chastisement?” 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: "Just think: If your water were to dry up in the morning who will bring you water from a fresh, flowing stream?" 30
