The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 And We place therein gardens of the date-palms and vines; and We therein cause to gush forth springs. 34 That they may eat of the fruit thereof, and their hands did not make it; 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 it of the day and lo, they are 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 for the moon We have appointed mansions till she return like an old shrivelled palm-leaf. 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 forefathers in a laden ship. 41 And We have created for them similar ships, in which they now 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 unless it be by an act of mercy from Us and a grant of life for a [further span of] time. 44 And when it is said to them: "Beware of that which is before you (worldly torments), and that which is behind you (torments in the Hereafter), in order that you may receive Mercy (i.e. if you believe in Allah's Religion Islamic Monotheism, and avoid polytheism, and obey Allah with righteous deeds). 45 Yet there never comes to them any sign of their Lord's signs, but they turn away from it. 46 And when it is said to them, "Spend from that which Allah has provided for you," those who disbelieve say to those who believe, "Should we feed one whom, if Allah had willed, He would have fed? You are not but in clear error." 47 And they say: When will this threat come to pass, if you are 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
