There is a sign in the dead earth for them which We quicken, and produce from it grain which they eat. 33 We have placed in it gardens of date palms and vines, and caused springs to gush [forth] from it, 34 So 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 there is a sign in the night for them. We strip off the day from it and they are left in darkness, 37 And the sun runs on to a term appointed for it; that is the ordinance of the Mighty, the Knowing. 38 And We have appointed positions for the moon till it returns like an old branch of the date palm. 39 The sun shall not outstrip the moon, nor shall the night outstrip the day. Each is floating in an orbit. 40 That We bore their progeny in the laden ark is a sign for them; 41 And We created for them from the likes of it that which they 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, 'Fear what is before you and what is behind you; haply you will 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 which Allah has given you' the unbelievers say to the believers: 'Are we to feed those whom Allah can feed if He chooses? Surely, you are only in clear error' 47 They say: “When will this threat (of Resurrection) come to pass? Tell us if indeed 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
