The physical growth of those whom We grant a long life will be reversed. Will you then not understand? 68 And We have not taught him (Muhammad) poetry, nor is it meet for him. This is naught else than a Reminder and a Lecture making plain, 69 That it may warn him who would have life, and (that) the word may prove true against the unbelievers. 70 Do they not see that We have created cattle for them, out of what Our hands have wrought, so they are their masters? 71 We have subjected these to them, so that some may be used for riding and some for food, 72 And therein they have advantages and drinks; will they not then be grateful? 73 They have set up other gods besides God, hoping to be helped by them, 74 They are not able to give them succour; whereas they shall be against them host brought forward. 75 However, be not grieved by the sayings of those [who deny the truth]: verily, We know all that they keep secret as well as all that they bring into the open. 76 Has not man regarded how that We created him of a sperm-drop? Then lo, he is a manifest adversary. 77 And he makes comparisons for Us, and forgets his own (origin and) Creation: He says, "Who can give life to (dry) bones and decomposed ones (at that)?" 78 Say, "He who brought them into being in the first instance will give them life again: He has knowledge of every type of creation: 79 He has created fire for you out of the green tree from which you can kindle other fires. 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 glory to Him in Whose hands is the dominion of all things: and to Him will ye be all brought back. 83
