There is a sign in the dead earth for them which We quicken, and produce from it grain which they eat. 33 And We have placed therein gardens of the date-palm and grapes, and We have caused springs of water to gush forth therein, 34 So that they may eat of its fruit; yet it was not done by their hands. Then why do they not acknowledge 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 And a sign unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 While the sun keeps revolving in its orbit. This is the dispensation of the mighty, all-knowing (God). 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 It is not permitted to the Sun to catch up the Moon, nor can the Night outstrip the Day: Each (just) swims along in (its own) orbit (according to Law). 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 And We have created for them similar (vessels) on which they 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 by Our mercy that they are granted provision for a time. 44 When it is said to such people: “Guard yourselves against what is ahead of you and what has preceded you that mercy be shown to you” (they pay scant heed to it). 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 And 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 Therefore neither able to make a will, nor returning to their homes. 50
