Evidence (of the truth) for them is how We revived the dead earth 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 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 the night is another Sign for them. We strip the day from it and they become plunged in darkness. 37 The sun is running its course to its appointed place. That is the ordaining of the All-Mighty, the All-Knowing. 38 And We have appointed positions for the moon till it returns like an old branch of the date palm. 39 The sun cannot overtake the moon, nor can the night outpace the day: each floats in [its own] orbit. 40 And a sign for them is that We carried their seed in the laden ship, 41 and We have created for them the like of it whereon they ride; 42 Should We so wish, We can drown them, and there will be none to heed their cries of distress, nor will they be rescued. 43 save as a mercy from Us, and enjoyment for a while. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 45 and whenever a revelation out of their Lord's revelations comes to them, they ignore 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 promise come to pass, if what you say is true?" 48 They will not have to wait long. When the Day of Judgment comes, it will only take a single blast of sound to strike them while they are quarrelling with one another. 49 and they will not even be able to make a testament, nor to return to their households. 50
