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 might eat of its fruits and their hands' labour. What, will they not be thankful? 35 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which they do not know. 36 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 The sun is running its course to its appointed place. That is the ordaining of the All-Mighty, the All-Knowing. 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 It is not for the sun to overtake the moon, nor does the night outstrip the day. They all float, each in an orbit. 40 And a sign for them is that We carried their seed in the laden ship, 41 And We have created for them similar (vessels) on which they ride. 42 And if We will, We shall drown them, and there will be no shout (or helper) for them (to hear their cry for help) nor will they be saved. 43 Unless by mercy from Us, and as a comfort for a while. 44 And when it is said to them, “Beware of what is before you and what is behind you, in the hope of your gaining mercy”, they turn away! 45 and no message of their Sustainer's messages ever reaches them without their turning away from it. 46 And when it is said to them, "Spend from that which Allah has provided for you," those who disbelieve say to those who believe, "Should we feed one whom, if Allah had willed, He would have fed? You are not but in clear error." 47 And they say: when will this promise be fulfilled if ye say sooth? 48 They await but one Shout, which will surprise them while they are disputing. 49 Therefore neither able to make a will, nor returning to their homes. 50
