And a sign for them is the dead land. We gave it life, and We brought forth from it grains, so that they eat thereof. 33 And We have placed in it gardens of dates and grapes, and We have made springs of water in it. 34 so that they may consume the fruits and whatever their hands prepare. 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 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 And the sun runneth to its appointed term: that is the disposition of the Mighty, the Knowing. 38 And the moon! For it We have decreed mansions till it reverteth like the old branch of a palm-tree. 39 It is not for the sun to catch up with the moon, nor does the night surpass the day; and each one of them floats in its orbit. 40 That We bore their progeny in the laden ark is a sign for them; 41 and created for them similar things to ride. 42 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 Unless by mercy from Us, and as a comfort for a while. 44 When they are told, "guard yourselves against what is before you and what is behind you, in order that you may be shown mercy," [they turn away]. 45 And there comes not to them a communication of the communications of their Lord but they turn aside from it. 46 When they are told: "Spend of what God has given you," the unbelievers say to those who believe: "Why should we feed those whom God should have fed if He pleased?" You are only in palpable error. 47 And they say: when will this promise be fulfilled if ye say sooth? 48 They are only waiting for a single blast that will seize them, but they will go on contending. 49 then they will not be able to make any testament, nor will they return to their people. 50
