Before Muhammad died this great religious leader supposedly wrote the Koran (Qu'ran, meaning that which is uttered) which in part, is a collection of fragments of other beliefs. Muhammad reportedly went into a seizure prior to reciting the book. This book in turn was then copied with true fundamentalist fervour and is, according to Islamic scholars, as good a record of the original as possible. Of course, for the most part, having been copied from other beliefs and altered to suit, many of the stories are in parallel to the Old Testament. Such as Abraham having two wives, one named Sarah and one called Haggai. The Koran tells us that Haggai having given birth to Abraham's child was sent off into the wilderness where her offspring became the fore fathers of the Arabs. In fact, much interbreeding still occurred in Muhammad's day between Jews and Arabs and thus traditions were easily passed on, such as Old Testament stories. It is plainly obvious upon reading the Koran and the Old Testament that they are intrinsically linked together both in content and spiritual ideology.
