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 make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 So 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 Of the signs for them is how We separated the day from the night and thus they remained in darkness; 37 The sun, too, follows its determined course laid down for it by the Almighty, the All Knowing. 38 how We ordained the moon to pass through certain phases until it seems eventually to be like a bent twig; 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 to them is that We bear their offspring in the laden ship. 41 and created for them similar things to 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 comfort for a while. 44 Whenever they are told to guard themselves against sin and the forth coming torment so that perhaps they could receive mercy 45 Indeed, not one of your Lord's signs comes to them without their turning 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 They say, "When will this promise be fulfilled, if you are truthful?" 48 The Truth is that they are waiting for nothing but a mighty Blast to seize them the while they are disputing (in their worldly affairs), 49 then they will not be able to make any testament, nor will they return to their people. 50
