We almost strayed from our purpose. It is our intention (now) to stop with this First Book which is concerned with the nature of civilization and the accidents that go with it. We have dealt - as we think, adequately - with the problems connected with that. Perhaps some later (scholar), aided by the divine gifts of a sound mind and of solid scholarship, will penetldte into these problems in greater detail than we did here. A person who creates a new discipline does not have the task of enumerating (all) the (individual) problems con­nected with it. His task is to specify the subject of the discipline and its various branches and the discussions connected with it. His successors, then, may gradually add more problems, until the (discipline) is completely (presented).

"God knows, and you do not know." 1961

The author of the book - God forgive him!-says: I completed the composition and draft of this first part, before revision and correction, 1962 in a period of five months ending in the middle of the year 779 [November, 1377]. Thereafter, I revised and corrected the book, and I added to it the history of the (various) nations, as I mentioned and proposed to do at the beginning of the work.

Knowledge comes only from God, the strong, the wise.
