And a sign to them is the dead earth: We give life to it and bring forth from it grain so they eat of it. 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 so that they might eat of its fruit and the labor of their hands. Will they not give thanks? 35 All glory belongs to the One Who has created pairs out of what grow from the earth, out of their soul and out of that which 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 And the sun runs on to a term appointed for it; that is the ordinance of the Mighty, the Knowing. 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 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 And a sign for them is that We lodged them in a laden ship, while they were in their forefathers backs. 41 We have created for them the like of it in which they ride. 42 and [that,] if such be Our will, We may cause them to drown, with none to respond to their cry for help: and [then] they cannot be saved, 43 except Our mercy which could enable them to enjoy themselves for an appointed time. 44 When they are told, "Fear ye that which is before you and that which will be after you, in order that ye may receive Mercy," (they turn back). 45 None of the signs of their Lord ever comes to them but they turn away from it. 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 They will not (have to) wait for aught but a single Blast: it will seize them while they are yet disputing among themselves! 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
