Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 And We have placed therein gardens of the date-palm and grapes, and We have caused springs of water to gush forth therein, 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 Of the signs for them is how We separated the day from the night and thus they remained in darkness; 37 And the sun -- it runs to a fixed resting-place; that is the ordaining of the All-mighty, the All-knowing. 38 And the moon! For it We have decreed mansions till it reverteth like the old branch of a 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 That We bore their progeny in the laden ark is a sign for them; 41 and created for them similar things to ride. 42 We drown them if We will, then they have none to cry to, nor can they be saved, 43 unless it be a mercy from us, and as an enjoyment for a season. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 45 And no sign comes to them from the signs of their Lord except that they are from it turning away. 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 be fulfilled, if ye are truthful? 48 They await but one Shout, which will surprise them while they are disputing. 49 then they will not be able to make any testament, nor will they return to their people. 50
