A token unto them is the dead earth. We revive it, and We bring forth from it grain so that they eat thereof; 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 That they may eat of His fruit. And their hands have not produced it, so will they not be grateful? 35 Purity is to Him Who created all pairs, from what the earth grows, and of themselves, and from the things they do not know. 36 And a sign unto them is the night. We draw off the day therefrom, and lo! they are darkened. 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 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 carried their offspring in the laden Ark (of Noah). 41 And We have created for them similar (vessels) on which they ride. 42 If it were Our will, We could drown them: then there would be no helper [to hear their cry], nor could they be saved. 43 Unless it be a mercy from Us, and as an enjoyment for a while. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 Never does any Sign of their Lord come to them, but they turn away 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
