There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 We have laid out gardens of dates and grapes upon it, and made springs of water flow, 34 that they might eat of its fruits and their hands' labour. What, will they not be thankful? 35 Glory be to Him Who created all the sexual pairs, of that which the earth groweth, and of themselves, and of that which they know not! 36 They have a sign in the night: We withdraw from it the [light of] day -- and 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 how We ordained the moon to pass through certain phases until it seems eventually to be like a bent twig; 39 The sun cannot overtake the moon, nor can the night outpace the day: each floats in [its own] orbit. 40 That We bore their progeny in the laden ark is a sign for them; 41 And We have created for them similar (vessels) on which they ride. 42 We drown them if We will, then they have none to cry to, nor can they be saved, 43 save as a mercy from Us, and enjoyment for a while. 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 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 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 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 And they will not be able [to give] any instruction, nor to their people can they return. 50
