Hayward has been noted for weaving together “classical Islamic knowledge and methodologies and the source-critical Western historical method to make innovative yet carefully reasoned sense of complex historical issues".
The Warrior Prophet: Muhammad and War is his latest book to use this approach. The book eschews the traditional Islamic explanation that Muhammad excelled at warfare simply because he was a prophet and was therefore good at everything. Hayward argues that this incomplete explanation ignores Muhammad's
agency and hides his human aptitude and brilliance. Muhammad, he argues, was himself an astute and skilled strategist and warrior who understood the necessity of warfare as well as its transformational power. At 457 pages, it took Hayward "about a decade of on-and-off work to complete." ==Reviews==
