The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 34 That they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which they do not know. 36 They have a sign in the night: We withdraw from it the [light of] day -- and they are left in darkness. 37 And the sun runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, the All-Knowing. 38 And (as for) the moon, We have ordained for it stages till it becomes again as an old dry palm branch. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 That We bore their progeny in the laden ark is a sign for them; 41 We have created for them the like of it in which they ride. 42 We drown them if We will, then they have none to cry to, nor can they be saved, 43 Except as a mercy from Us and provision for a time. 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 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 with which Allah has provided you," those who disbelieve say to those who believe: "Shall we feed those whom, if Allah willed, He (Himself) would have fed? You are only in a plain error." 47 They say, "When will this promise be fulfilled, if you are truthful?" 48 They do not await except one blast which will seize them while they are disputing. 49 Then they would not be able to make a will, or go back to their people. 50
