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 [thus it is:] We have not imparted to this [Prophet the gift of] poetry, nor would [poetry] have suited this [message]: it is but a reminder and a [divine] discourse, clear in itself and clearly showing the truth, 69 That he or it (Muhammad SAW or the Quran) may give warning to him who is living (a healthy minded the believer), and that Word (charge) may be justified against the disbelievers (dead, as they reject the warnings). 70 Have they not seen what We have created from the labor of Our own hands? We have given them cattle. 71 And We have subdued them unto them, so that some of them they have for riding and on some of them they feed? 72 And for them in the animals are numerous different benefits and drinks; so will they not be grateful? 73 Yet they have taken, apart from God, gods; haply they might be helped. 74 They are not able to give them succour; whereas they shall be against them host brought forward. 75 So let not their speech grieve you. Indeed, We know what they conceal and what they declare. 76 Has not man regarded how that We created him of a sperm-drop? Then lo, he is a manifest adversary. 77 And he hath coined for Us a similitude, and hath forgotten the fact of his creation, saying: Who will revive these bones when they have rotted away? 78 (Muhammad), tell him, "He who gave them life in the first place will bring them back to life again. He has the best knowledge of all creatures. 79 He who produces fire for you from green trees and from this you kindle fire." 80 Is not He who created the heavens and the earth Able to create the likes of them? Yes, [it is so]; and He is the Knowing Creator. 81 His affair, when He intendeth a thing, is only that He saith unto it: be, and it becometh. 82 So glory be to Him who has control over all things. It is to Him that you will all be brought back. 83
