Likewise, there is a fifth existent that is the basis of these pillars, and there is a disagreement among the owners of the science of nature regarding consideration. Al-Hakim mentioned it in the Istiqas and he did not mention anything in it that the observer would stop at. We did not know this in terms of my reading of the science of nature according to its people, but rather it came into play with a friend of mine, and he is In his hand, and he was busy obtaining medical knowledge, he asked me if I would pass it on to him from the point of view of our knowledge of these things, from the point of view of discovery, not from the point of view of reading and looking, so he read it to us, and I noticed from him this disagreement that I referred to. From there I learned it, and if not that, I would not have known whether anyone disagreed with it or not, for it is not. We have in it nothing but the true thing that it is, and we have no disagreement.
