Evidence (of the truth) for them is how We revived the dead earth 33 And there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 so that they may eat its fruit, though it was not their hands that made this. Will they not then be grateful? 35 Holy is He Who created all things in pairs, whether it be of what the earth produces, and of themselves, and of what 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 And the sun runneth to its appointed term: that is the disposition of the Mighty, the 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 It is not for the sun to overtake the moon, nor does the night outstrip the day. They all float, each in an orbit. 40 And a sign for them is that We carried their offspring in the laden Ark (of Noah). 41 And We created for them from the likes of it that which 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 It is only by Our mercy that they are granted 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 revelation out of their Lord's revelations comes to them, they ignore it. 46 And when it is said to them: Spend out of what Allah has given you, those who disbelieve say to those who believe: Shall we feed him whom, if Allah please, He could feed? You are in naught but clear error. 47 And they say: When will this threat come to pass, if you are truthful? 48 They will not (have to) wait for aught but a single Blast: it will seize them while they are yet disputing among themselves! 49 Then they will be unable to make a will, nor shall they return to their kinsmen. 50
