The attack and subsequent destruction of the World Trade Towers in New York City on September 11, 2001, motivated me to pose this question. Does the Qur’an mention a Holy War against those who do not believe in Allah as God and in Mohammed as God’s Prophet? In studying the Qur’an, I discovered many biblical events and characters that seem to run parallel. Or do they? Intrigued, I decided to bring all references together into one file and compare them to each other. The result is this work, which I want to present to the reader for his/her scrutiny.
