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 have placed in it gardens of dates and grapes, and We have made springs of water in it. 34 So that they may eat from its fruits, whereas they are not manufactured by their hands! So will they not be grateful? 35 Glory be to Him Who created pairs of all things, of what the earth grows, and of their kind and of what 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 runneth to its appointed term: that is the disposition of the Mighty, the Knowing. 38 And the moon, We have measured for it mansions (to traverse) till it returns like the old dried curved date stalk. 39 [and] neither may the sun overtake the moon, nor can the night usurp the time of day, since all of them float through space [in accordance with Our laws]. 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 But when it is said to them, "Beware of what is before you and what is behind you; perhaps you will receive mercy... " 45 And whenever a sign comes to them from the signs of their Lord, they always turn away from it! 46 And when it is said to them: 'Spend of that which Allah has given you' the unbelievers say to the believers: 'Are we to feed those whom Allah can feed if He chooses? Surely, you are only in clear error' 47 They say, "When will this promise be fulfilled, if you are truthful?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 Then they will not be able to make bequest, nor they will return to their family. 50
