And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it they eat. 33 And We have placed in it gardens of dates and grapes, and We have made springs of water in it. 34 That they may eat of the fruit thereof; and their hands worked it not. Will they not, therefore, give 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 there is a sign in the night for them. We strip off the day from it and they are left in darkness, 37 While the sun keeps revolving in its orbit. This is the dispensation of the mighty, all-knowing (God). 38 We have determined the stations of the moon, so that (after its wanderings) it returns as a dried up inflorescent spike of dates. 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 unto them is that We bear their offspring in a laden ship. 41 And We have created for them similar ships, in which they now 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 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 Yet there never comes to them any sign of their Lord's signs, but they turn away from it. 46 And when they are told, "Spend ye of (the bounties) with which Allah has provided you," the Unbelievers say to those who believe: "Shall we then feed those whom, if Allah had so willed, He would have fed, (Himself)? Ye are in nothing but manifest error." 47 And they say: When will this threat come to pass, 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
