He it is Who made the earth smooth for you, therefore go about in the spacious sides thereof, and eat of His sustenance, and to Him is the return after death. 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 have you become so unafraid that He who is in Heaven will not send a violent wind to shower stones at you? Then you will know the import of My commination! 17 And verily those before them denied, then (see) the manner of My wrath (with 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 What other army do you have to help you apart from Ar-Rahman? The unbelievers are surely lost in delusion. 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: "[God is] He who has brought you [all] into being, and has endowed you with hearing, and sight, and hearts: [yet] how seldom are you grateful!" 23 Say: "It is He Who has multiplied you through the earth, and to Him shall ye be gathered together." 24 But they [only] ask, "When is this promise to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 25 Say: 'The knowledge (of that) is with Allah; I am only a clear warner' 26 Yet in the end, when they shall see that [fulfilment] close at hand, the faces of those who were bent on denying the truth will be stricken with grief; and they will be told, "This it is that you were [so derisively] calling for!" 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 thou: He is the Compassionate; in Him we have believed, and in Him we have put our trust. And anon ye will know who it is that is in error manifest. 29 Say, "Have you not thought that if your water was to dry up, who would bring you water from the spring?" 30
