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 Have they not seen what We have created from the labor of Our own hands? We have given them cattle. 71 And have subjected the animals for them, so they ride some animals and eat some? 72 Benefits and (divers) drinks have they from them. Will they not then give thanks? 73 And they have taken beside Allah gods, hoping that haply they may be succoured. 74 They are not able to give them succour; whereas they shall be against them host brought forward. 75 So let not their speech, then, grieve you (O Muhammad SAW). Verily, We know what they conceal and what they reveal. 76 Beholdest not man that We have created him from a sperm? Yet lo! he is a manifest disputer? 77 And he puts forth for Us a parable, and forgets his own creation. He says: "Who will give life to these bones when they have rotted away and became dust?" 78 Say: "He who brought them into being in the first instance will give them life [once again,] seeing that He has full knowledge of every act of creation: 79 Who gave you fire from a green tree, with which you ignite the flame." 80 Is the One who has created the heavens and the earth not able to create another creature like the human being? He certainly has the power to do so. He is the Supreme Creator and is All-knowing. 81 Whenever He decides to create something He has only to say, "Exist," and it comes into existence. 82 So exalted is He in whose hand is the realm of all things, and to Him you will be returned. 83
