Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 That they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Limitless in His glory is He who has created opposites in whatever the earth produces, and in men's own selves, and in that of which [as yet] they have no knowledge. 36 Of the signs for them is how We separated the day from the night and thus they remained in darkness; 37 And the sun runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, the All-Knowing. 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere. 40 And a sign for them is that We carried their seed in the laden ship, 41 And We made similar vessels for them to ride. 42 And if We please, We can drown them, then there shall be no succorer for them, nor shall they be rescued 43 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 44 When they are told, "guard yourselves against what is before you and what is behind you, in order that you may be shown mercy," [they turn away]. 45 Never does any Sign of their Lord come 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 Further, they say, "When will this promise (come to pass), if what ye say is true?" 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
