A token unto them is the dead earth. We revive it, and We bring forth from it grain so that they eat thereof; 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 that they might eat of its fruits. It was not their hands that made them. Will they not, then, give thanks? 35 Holy is He who created all things in pairs; of what the earth grows, and of themselves, and other things which they do not know. 36 A token unto them is night. We strip it of the day, and lo! 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 in phases till it returns like an old palmbranch. 39 It behoves not the sun to overtake the moon, neither does the night outstrip the day, each swimming in a sky. 40 That We bore their progeny in the laden ark is a sign for them; 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 Unless by mercy from Us and as comfort for a while. 44 And when it is said unto them: fear that which is before you and that which is behind you, that haply ye may find mercy, they withdraw. 45 Indeed, not one of your Lord's signs comes to them without their turning away from it, 46 And when it is said to them, “Spend in Allah’s cause, from what Allah has provided you”, the disbelievers say regarding the believers, “Shall we feed these, whom if Allah willed, would have fed? You are not but in open error!” 47 They say: “When will this threat (of Resurrection) come to pass? Tell us if indeed 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 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
