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 Have ye taken security from Him Who is in the heaven that He will not cause the earth to swallow you when lo! it is convulsed? 16 Do you feel secure that He who is in the heaven will not loose against you a squall of pebbles then you shall know how was My warning. 17 Those before them had also denied. And how was My punishment then! 18 Did they not see the birds above them, stretching out, and flapping their wings. No one keeps them up in the sky except the Beneficent God. He certainly watches over all things. 19 Or who is it that will be a host for you to assist you besides the Beneficent Allah? The unbelievers are only in deception. 20 Or who is this that shall provide for you if He withholds His provision? No, but they persist in disdain and aversion. 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 has brought you into being, and has given you hearing and sight, and has given you hearts to think and understand. How seldom do you give thanks!” 23 Say: "It is He who has multiplied you on earth; and it is unto Him that you shall be gathered [on resurrection]." 24 They say: "When will this promise (i.e. the Day of Resurrection) come to pass? if you are telling the truth." 25 Say: The knowledge is with Allah only, and I am but a plain warner; 26 At length, when they see it close at hand, grieved will be the faces of the Unbelievers, and it will be said (to them): "This is (the promise fulfilled), which ye were calling for!" 27 Say: "See ye?- If Allah were to destroy me, and those with me, or if He bestows His Mercy on us,- yet who can deliver the Unbelievers from a grievous Penalty?" 28 Say: 'He is the Merciful. In Him we believe and in Him we put all our trust. Indeed, you shall soon know who is in clear error' 29 Say (O Muhammad SAW): "Tell me! If (all) your water were to be sunk away, who then can supply you with flowing (spring) water?" 30
