There is a sign in the dead earth for them which We quicken, and produce from it grain which they eat. 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 so that they may eat its fruit, though it was not their hands that made this. Will they not then be grateful? 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 a sign for them is the night. We remove from it [the light of] day, so they are [left] in darkness. 37 And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 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 Another Sign for them is that We carried all their offspring in the laden vessel 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 Except by way of Mercy from Us, and by way of (world) convenience (to serve them) for a time. 44 When it is said to them: "Beware of what is before you and what is past, that you may be treated with kindness;" 45 yet never any sign of the signs of their Lord comes to them, but they are 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 And they say: "When will this promise (i.e. Resurrection) be fulfilled, if you are truthful?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
