Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 And there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 So that they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Holy is He who created all things in pairs; of what the earth grows, and of themselves, and other things which they do not know. 36 And a sign for them is the night; We strip it of the day and lo, 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 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 a sign unto them is that We bear their offspring in a laden ship. 41 And We created for them from the likes of it that 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 But (by) mercy from Us and for enjoyment till a time. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 45 And whenever a sign comes to them from the signs of their Lord, they always turn away from it! 46 And when they are told, "Spend ye of (the bounties) with which Allah has provided you," the Unbelievers say to those who believe: "Shall we then feed those whom, if Allah had so willed, He would have fed, (Himself)? Ye are in nothing but manifest error." 47 And they say, "When is this promise, if you should be 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 and they will not even be able to make a testament, nor to return to their households. 50
