Evidence (of the truth) for them is how We revived the dead earth 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 eat of the fruit thereof, though it was not their hands that made it. Will they not, then, 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 for them is the night, We withdraw therefrom the day, and behold, they are in darkness. 37 And the sun -- it runs to a fixed resting-place; that is the ordaining of the All-mighty, the All-knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 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 lodged them in a laden ship, while they were in their forefathers backs. 41 And have created for them of the like thereof whereon 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 except Our mercy which could enable them to enjoy themselves for an appointed time. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 and whenever a revelation out of their Lord's revelations comes to them, they ignore it. 46 Thus, when they are told, "Spend on others out of what God has provided for you as sustenance," those who are bent on denying the truth say unto those who believe, "Shall we feed anyone whom, if [your] God had so willed, He could have fed [Himself]? Clearly, you are but lost in error!" 47 And they say: "When will this promise (i.e. Resurrection) be fulfilled, if you are truthful?" 48 They will not (have to) wait for aught but a single Blast: it will seize them while they are yet disputing among themselves! 49 then they will not be able to make any testament, nor will they return to their people. 50
