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 there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 so that they may consume the fruits and whatever their hands prepare. Will they not then be grateful? 35 Glory be to Him Who created all the sexual pairs, of that which the earth groweth, and of themselves, and of that which they know not! 36 And there is a sign in the night for them. We strip off the day from it and they are left in darkness, 37 The sun, too, follows its determined course laid down for it by the Almighty, the All Knowing. 38 and [in] the moon, for which We have determined phases [which it must traverse] till it becomes like an old date-stalk, dried-up and curved: 39 Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 and We have created for them the like of it whereon they ride; 42 We could have drowned them if We pleased, and none would have answered their cry for help, nor would they have been saved, 43 Unless by Our benevolence, to reap advantage for a time. 44 When it is said to them: 'Have fear of that which is before you and behind you in order that you find mercy' 45 And no sign comes to them from the signs of their Lord except that they are from it turning away. 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 And they say: "When will this promise come to pass, if what you say is true?" 48 They are only waiting for a single blast that will seize them, but they will go on contending. 49 Then they cannot make bequest, nor can they return to their own folk. 50
