Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 We have laid out gardens of dates and grapes upon it, and made springs of water flow, 34 That they may eat of the fruit thereof, and their hands did not make it; will they not then be grateful? 35 Glory be to Him, who created all the pairs of what the earth produces, and of themselves, and of what they know not. 36 And a sign for them is the night, We withdraw therefrom the day, and behold, they are in darkness. 37 And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 Neither does it lie in the sun's power to overtake the moon nor can the night outstrip the day. All glide along, each in its own orbit. 40 And a sign for them is that We lodged them in a laden ship, while they were in their forefathers backs. 41 and created for them similar things to ride. 42 We could have drowned them if We pleased, and none would have answered their cry for help, nor would they have been saved, 43 Unless by mercy from Us and as comfort for a while. 44 When they are told, "Fear ye that which is before you and that which will be after you, in order that ye may receive Mercy," (they turn back). 45 and whenever a revelation out of their Lord's revelations comes to them, they ignore it. 46 Thus, when they are told, "Spend on others out of what God has provided for you as sustenance," those who are bent on denying the truth say unto those who believe, "Shall we feed anyone whom, if [your] God had so willed, He could have fed [Himself]? Clearly, you are but lost in error!" 47 The unbelievers say, "When will the Day of Judgment come if what you say is at all true?" 48 [And they are unaware that] nothing awaits them beyond a single blast [of God's punishment,] which will overtake them while they are still arguing - [against resurrection]: 49 They will have no time to make a will, nor shall they return to their own people. 50
