It is He who made the earth subservient to you that you may travel all around it, and eat of things He has provided; and to Him will be your resurrection. 15 Are you so unafraid that He who is in Heaven will not open up the earth to swallow you, when it will begin to tremble? 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 Those that were before them also cried lies; then how was My horror! 18 Have they not seen the birds above them spreading out their wings and closing them? Naught upholdeth them save the Beneficent. Lo! He is Seer of all things. 19 What other army do you have to help you apart from Ar-Rahman? The unbelievers are surely lost 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 Can one who walks with his head hanging down be better guided that one who walks with his head upright? 22 Say: He it is Who brought you into being and made for you the ears and the eyes and the hearts: little is it that you give thanks. 23 Say: "It is He Who has multiplied you through the earth, and to Him shall ye be gathered together." 24 They ask: 'When will this promise come, if you speak truthfully' 25 Say: The knowledge is with Allah only, and I am but a plain warner; 26 When they realise it has come upon them, distraught will be the faces of unbelievers. They will be told: "This is what you asked for." 27 Say, "Have you thought: if God destroys me and those who are with me, or treats us mercifully, then who will protect those who deny the truth from a painful chastisement?" 28 Say: "He is the Most Beneficent (Allah), in Him we believe, and in Him we put our trust. So you will come to know who is it that is in manifest error." 29 Say: 'What think you? If in the morning your water should have vanished into the earth, then who would bring you running water?' 30
