It is He Who has made the earth manageable for you, so traverse ye through its tracts and enjoy of the Sustenance which He furnishes: but unto Him is the Resurrection. 15 Do you feel secure that the One in the heavens will not cause you to sink into the earth when it is violently shaking? 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 indeed those before them had denied – therefore how did My rejection turn out! 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 Who is he that can be an army unto you and succour you, beside the Compassionate! The infidels are but in delusion. 20 Is there anyone who will provide you with sustenance if God were to deny you sustenance? In fact, they obstinately persist in their transgression and hatred. 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 created you, and endowed you with hearing (ears), seeing (eyes), and hearts. Little thanks you give. 23 Say, "It is He who has multiplied you throughout the earth, and to Him you will be gathered." 24 And they say, “When will this promise come, if you are truthful?” 25 Say, "The knowledge is only with Allah, and 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: 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 Merciful; we have believed in Him, and upon Him we have relied. And you will [come to] know who it is that is in clear error." 29 Say [unto those who deny the truth]: "What do you think? If of a sudden all your water were to vanish underground, who [but God] could provide you with water from [new] unsullied springs?" 30
