He it is Who made the earth subservient to you. So traverse in its tracks and partake of the sustenance He has provided. To Him will you be resurrected. 15 Do you feel secure that He who is in the heaven will not cause the earth to swallow you up while it shakes? 16 Or are you secure of those in the heaven that He should not send down upon you a punishment? Then shall you know how was My warning. 17 Those who have gone before you also belied (their Messengers) then how was My disapproval! 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 Who is he that can be an army unto you and succour you, beside the Compassionate! The infidels are but in delusion. 20 Who is he that can provide for you if He should withhold His provision? Nay, but they continue to be in pride, and (they) flee (from the truth). 21 Can one who walks with his head hanging down be better guided that one who walks with his head upright? 22 Say, "It is He who has produced you and made for you hearing and vision and hearts; little are you grateful." 23 Say: "It is He who dispersed you all over the earth, and to Him you will be gathered." 24 But they say: "When will this promise come to pass, if what you say is true?" 25 Say, "God knows best. I am only one who gives warning". 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 (O dear Prophet Mohammed – peace and blessings be upon him), “What is your opinion –Allah may either destroy me and those with me, or have mercy on us – so who is such that will protect the disbelievers from the painful punishment?” 28 Proclaim, “He only is the Most Gracious – we have accepted faith in Him and have relied only upon Him; so you will now realise who is in open 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
