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 Do you feel secure that He who is in heaven will not cause the earth to swallow you, the while it rocks? 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 belied (the Messengers of Allah), then how terrible was My denial (punishment)? 18 Have they not seen the birds above them expanding (their wings) and contracting (them)? What is it that withholds them save the Beneficent Allah? Surely He sees everything. 19 Or who is this that shall be a host for you to help you, apart from the All-merciful? The unbelievers are only 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 Then is one who walks fallen on his face better guided or one who walks erect on a straight path? 22 Say, "It is He who brought you into being, and made ears and eyes and hearts for you, yet you are seldom grateful." 23 Say: "It is He Who has multiplied you through the earth, and to Him shall ye be gathered together." 24 But they say: "When will this promise come to pass, if what you say is true?" 25 Say, "The knowledge is only with Allah, and I am only a clear warner." 26 But when they see it drawing near, the faces of those who deny the truth will turn gloomy and they will be told, "This is what you were calling for." 27 Say: 'What think you? If God destroys me and those with me, or has mercy on us, then who will protect the unbelievers from a painful chastisement?' 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: 'What do you think. If your water should sink into the earth in the morning, who then would bring you running water' 30
