We feel honored to present to our respectable readers the English edition of the biography of Prophet Muhammad (PBUH) after it has been published more than 30 times in Arabic and after the publication of the Romanian version which was adopted by the University of Craiova as a source for introducing the Prophet of Islam to the world. It is high time for us that we present a correct conception of the Prophet of Islam amidst the hustle and bustle taking place between the East and the West nowadays, particularly after the break out of the bloody uprisings in the Middle East against dictatorships and oppressive regimes. So, was Islam really a message of horror and terror? Did Prophet Muhammad really make people embrace Islam by sword and war? This biography of Prophet Muhammad (PBUH) offers the readers a different answer; however, before going into more details I should mention that this biography was written 25 years ago. It only included a historical narration of the events in the Prophet's life in an easy language that brought together the main narrations of main historians without any personal interference concerning examining those narrations or criticizing them.
