Khalil Abdel-Karim said that his book "The formation period in the life of Mohammed," was historical research relying on a number of traditions about Mohammed’s life before the Qur’an was revealed to him. The head of the [banned] Azhar Scholars Front said that the writer showed no respect for religion, threatened national unity and should bear all the consequences of his crime. He added that he would have responded to the book as historical research instead of calling the author an unbeliever, if the book had used any scientific method.
