Evidence (of the truth) for them is how We revived the dead earth 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 That they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 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 to them is the night: We draw forth from it the day, then lo! they are in the dark; 37 And the sun -- it runs to a fixed resting-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 catch up with the moon, nor does the night surpass the day; and each one of them floats in its orbit. 40 And a sign for them is that We carried their forefathers in a laden ship. 41 We have created for them the like of it in 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 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 no sign comes to them from the signs of their Lord except that they are from it turning away. 46 When they are told to spend for the cause of God out of what He has provided for them for their sustenance, the disbelievers say to the believers, "Should we feed those whom God has decided to feed? You are in plain error." 47 And they say, "When is this promise, if you should be truthful?" 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 Then they cannot make bequest, nor can they return to their own folk. 50
