It is He who made the earth tame for you - so walk among its slopes and eat of His provision - and to Him is the 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 can you ever feel secure that He who is in heaven will not let loose against you a deadly stormwind, whereupon you would come to know how [true] My warning was? 17 Those who came before them also gave the lie (to the Messengers): then how awesome was My chastisement! 18 Have they not regarded the birds above them spreading their wings, and closing them? Naught holds them but the All-merciful. Surely He sees everything. 19 Or who is he that will be an army unto you to help you instead of the Beneficent? The disbelievers are in naught but illusion. 20 Or who is it that could provide for you if He withheld His provision? But they have persisted in insolence and aversion. 21 What! is he who goes prone upon his face better guided or he who walks upright upon a straight path? 22 Say thou: He it is who hath brought you forth and hath endowed you with hearing and sights and hearts. Little thanks it is ye give! 23 Say, “It is He Who has spread you out in the earth, and towards Him you will be raised.” 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 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, "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 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 to them: “Did you even consider: if all the water that you have (in the wells) were to sink down into the depths of the earth, who will produce for you clear, flowing water?” 30
