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 Do you feel secure that He who is in heaven will not cause the earth to sink beneath you and then begin to quake? 16 Or are ye secure that He Who is in the heaven will not send against you a whirlwind? Anon ye shall know what wise hath been My warning. 17 And indeed those before them had denied – therefore how did My rejection turn out! 18 Do they not observe the birds above them, spreading their wings and folding them? None, except the Merciful holds them. Surely, He sees all things. 19 Nay, who is there that can help you, (even as) an army, besides (Allah) Most Merciful? In nothing but delusion are the Unbelievers. 20 Or who is this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 21 Is then one who walks headlong, with his face grovelling, better guided,- or one who walks evenly on a Straight Way? 22 Say: 'It is He who has created you and given to you hearing, sight and hearts but little is it that you thank' 23 Say thou: He it is Who hath spread you over the earth, and unto Him ye shall be gathered. 24 And they say: When (will) this promise (be fulfilled), if ye are truthful? 25 Say: "As to the knowledge of the time, it is with Allah alone: I am (sent) only to warn plainly in public." 26 But when they shall see it nigh, the faces of those who disbelieve shall be sorry, and it shall be said; This is that which you used to call 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 Beneficent Allah, we believe in Him and on Him do we rely, so you shall come to know who it is that is in clear error. 29 Say, “What is your opinion – if in the morning all your water were to sink into the earth, then who is such who can bring you water flowing before you?” 30
