From around 610 A.D. to around 630 A.D., Muhammad stole passages from the Bible and added his insane imaginations to create the Koran.  Also, the first half of the Koran says “hate no one” and the second half of the Koran says “hate everyone.”  This has resulted in “schizophrenia” throughout the Muslim community and explains why insanity is more common among Muslims than non-Muslims.
