There is a sign in the dead earth for them which We quicken, and produce from it grain which they eat. 33 and [how] We make gardens of date-palms and vines [grow] thereon, and cause springs to gush [forth] within it, 34 so that they may consume the fruits and whatever their hands prepare. Will they not then be grateful? 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 for them is the night; We strip the day out of it, thereupon they are in darkness. 37 And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing. 38 And the moon -- We have determined it by stations, till it returns like an aged palm-bough. 39 It is not permitted to the sun that it should overtake the moon, nor can the night outstrip the day: each in an orbit, they float. 40 Another Sign for them is that We carried all their offspring in the laden vessel 41 and [that] We create for them things of a similar kind, on which they may embark [in their travels]; 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 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 44 When it is said to them: 'Have fear of that which is before you and behind you in order that you find mercy' 45 And no sign comes to them from the signs of their Lord except that they are from it turning away. 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 And they say, "When is this promise, if you should be truthful?" 48 [And they are unaware that] nothing awaits them beyond a single blast [of God's punishment,] which will overtake them while they are still arguing - [against resurrection]: 49 and they will not even be able to make a testament, nor to return to their households. 50
