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 produced therein grains from which they eat and established therein gardens of palms trees and vineyards and have made streams flow therein 34 so that they may eat its fruit, though it was not their hands that made this. Will they not then be grateful? 35 Glory be to Him, who created all the pairs of what the earth produces, and of themselves, and of what they know not. 36 A token unto them is night. We strip it of the day, and lo! they are in darkness. 37 While the sun keeps revolving in its orbit. This is the dispensation of the mighty, all-knowing (God). 38 And We have appointed positions for the moon till it returns like an old branch of the date palm. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And We made similar vessels for them to ride. 42 And if We will, We can drown them, so there would be no help in their distress, nor would they be saved. 43 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 44 When it is said to them: "Beware of what is before you and what is past, that you may be treated with kindness;" 45 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 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 also say, 'When shall this promise come to pass, if you speak truly?' 48 They do not await except one blast which will seize them while they are disputing. 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
