Norwegian historian Halvor Tjønn has written a biography of Muhammad the founder of Islam and Oslo publisher Kagge had agreed to publish the book and even listed it in last year’s fall catalog.

However the publisher has suddenly pulled out of the project and now refuses to give any explanations of why it will no longer publish the book.

According to the author there should be nothing in the book that would upset Muslims. There are no illustrations of Muhammad and all of the key references used in the work are from the 8th and 9th centuries.
