The Koran, the sacred book of Islam, and of more than a hundred millions of men, is the least original of all existing sacred books. Muslims agree in believing that it is from beginning to end, and word for word, inspired; and that it existed before the Creation on what is called the "Preserved Tablet." This tablet was brought by the Archangel Gabriel from the highest to the lowest heaven, whence it was dictated sura [chapter] by sura, verse by verse, and word by word, to the Prophet Muhammad. Its matter is, however, taken for the most part from the Old Testament, especially the narrative portions of the Pentateuch; from the New Testament; from the traditions of the ancient Arabs; and also from Zoroastrian and other scriptures or traditions. It is not likely that Muhammad used literary sources, except in a small measure. But there were Jews, Christians, Zoroastrians, and others in and around Arabia, and he must have learned from their lips the principal doctrines of their respective religions. Nevertheless, planless and fragmentary compilation though it be, the Koran, particularly in the earlier suras written at Mekka, has much of the grandeur and poetry of style and the passionate exaltation of a true prophet, the sincerity of whose zeal is unquestioned. _INTRODUCTORY_ The word "Koran," or "Quran,"[13] from a root _qara_ = to read, means literally "what is to be read," _i.e._, the written authority on all matters, religions, etc. It is the exact equivalent of the Rabbinical Hebrew word "Miqra" (from the Hebrew _qara_ = to read). The idea involved in both the Arabic and Hebrew words is that what is so designated is the ultimate authority deciding all questions. The Rabbis of post-Biblical times (compare the Jewish Qabbalah) regarded the Old Testament as an encyclopaedia of universal knowledge. In the best-known Muslim universities of modern times philosophy, science, and everything else are taught from the Koran, which is made in some way to contain implicitly the latest words of modern thought, invention, and discovery. The Koran did not exist as a whole until after the Prophet Muhammad's[14] death. It was then compiled by the order of Abu Bekr, the first Sunnite Caliph. Its contents were found written on palm leaves white stones, and other articles capable of being written on. The compilers depended, to a large extent, upon the memory of the prophet's first followers, but the Koran, as we now have it, existed without any appreciable divergence by the end of the first year, after Muhammad's death (A.D. 632). This Muslim Bible has no scheme or plan because it is an almost haphazard compilation of unconnected discourses, uttered on various unexplained occasions, and dealing with many incidents and themes. There is practically no editing, and no attempt is made to explain when, or how, or why the various speeches were delivered.
