There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 And We placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 34 that they might eat of its fruits and their hands' labour. What, will they not be thankful? 35 Glory be to Him Who created pairs of all things, of what the earth grows, and of their kind and of what they do not know. 36 And a sign for them is the night. We remove from it [the light of] day, so they are [left] in darkness. 37 And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. 38 And the moon, We have measured for it mansions (to traverse) till it returns like the old dried curved date stalk. 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 [it ought to be] a sign for them that We bear their offspring [over the seas] in laden ships, 41 And We have created for them the like of it, what they will ride on. 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 it be by an act of mercy from Us and a grant of life for a [further span of] time. 44 When it is said to such people: “Guard yourselves against what is ahead of you and what has preceded you that mercy be shown to you” (they pay scant heed to it). 45 Indeed, not one of your Lord's signs comes to them without their turning away from it, 46 And when it is said to them: 'Spend of that which Allah has given you' the unbelievers say to the believers: 'Are we to feed those whom Allah can feed if He chooses? Surely, you are only in clear error' 47 And they say, "When is this promise, if you should be truthful?" 48 They are only waiting for a single blast that will seize them, but they will go on contending. 49 Then they would not be able to make a will, or go back to their people. 50
