Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 and [how] We make gardens of date-palms and vines [grow] thereon, and cause springs to gush [forth] within it, 34 That they may eat of the fruit thereof, and their hands made it not. 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 And a sign for them is the night; We strip it of the day and lo, they are in darkness. 37 While the sun keeps revolving in its orbit. This is the dispensation of the mighty, all-knowing (God). 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 Neither does it lie in the sun's power to overtake the moon nor can the night outstrip the day. All glide along, each in its own orbit. 40 And a sign for them is that We carried their seed in the laden ship, 41 And We have created for them the like of it, what they will ride on. 42 and if We will, We drown them, then none have they to cry to, neither are they delivered, 43 unless it be by an act of mercy from Us and a grant of life for a [further span of] 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 And whenever a sign comes to them from the signs of their Lord, they always turn away from it! 46 and when they are told, "Give to others out of what God has provided for you," those who are bent on denying the truth say to the believers, "Why should we feed those whom God could feed if He wanted? You are clearly in error!" 47 They say, "When will this promise be fulfilled, if you are truthful?" 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
