But [let them always remember that] if We lengthen a human being's days, We also cause him to decline in his powers [when he grows old]: will they not, then, use their reason? 68 And We have not taught him poetry, nor is it meet for him; it is nothing but a reminder and a plain Quran, 69 So that he may warn him who is alive and feels, and justify the word against those who do not believe. 70 Do they not see that, among the things which Our hands have fashioned, We have created for them cattle of which they are the masters, 71 And that We have subjected them to their (use)? of them some do carry them and some they eat: 72 And they have (other) benefits from them (besides), and they get (milk) to drink, will they not then be grateful? 73 And yet they have taken gods, other than Allah, so that they might be helped! 74 They cannot help them, but they will be brought forward as a troop against those who worshipped them (at the time of Reckoning). 75 Therefore (O dear Prophet Mohammed – peace and blessings be upon him) do not grieve because of what they (the disbelievers) say; indeed We know what they conceal and what they disclose. 76 Has the human being not considered that We have created him from a drop of fluid. He is openly quarrelsome. 77 And he has struck for Us a similitude and forgotten his creation; he says, 'Who shall quicken the bones when they are decayed?' 78 Say, "He will give them life Who created them for the first time! for He is Well-versed in every kind of creation!- 79 He who produces fire for you from green trees and from this you kindle fire." 80 Is He who created the heavens and earth not able to create others like these people? Of course He is! He is indeed the Supreme Creator, the All Knowing: 81 when He decrees a thing, He need only say, "Be!" and it is. 82 So all glory to Him who holds all power over everything, to whom you will go back in the end. 83
