A former senior mujahidin figure and an ex-counter-terrorism analyst cooperating to write a book on the history and legacy of Arab-Afghan fighters in Afghanistan is a remarkable and improbable undertaking. Yet this is what Mustafa Hamid, aka Abu Walid al-Masri, and Leah Farrall have achieved with the publication of their ground-breaking work. The result of thousands of hours of discussions over several years, The Arabs at War in Afghanistan offers significant new insights into the history of many of today's militant Salafi groups and movements. By revealing the real origins of the Taliban and al-Qaeda and the jostling among the various jihadi groups, this account not only challenges conventional wisdom, but also raises uncomfortable questions as to how events from this important period have been so badly misconstrued.

"…a rare piece of original research into a subject that remains little understood and is often over-simplified. The book argues, correctly, that without understanding the early history of the jihadist movement we cannot hope to assess how the movement will evolve. It is also one of the few works to try to explain this history from the perspective of an early, active participant. … The Arabs at War in Afghanistan should therefore be essential reading for specialists trying to understand the Islamic State, and serve as a warning against any attempt to provide static descriptions of Salafi jihadism rather than seeing it as a continually evolving process." - War on the Rocks

"As Farrell's dialogue develops, she extracts intriguing nuggets of information from Hamid such as the participation of Afghan mujaheddin fighters in the first Gulf War; the early involvement of Pakistan’s spy agency, the ISI; divisions within the mujaheddin; and the rise of the Taliban. … As so many questions are being asked about what led to the rise of Islamic State, Farrell has done a commendable job in bringing us an alternative perspective on what historians will look back on as the defining period in the crisis now enveloping the Arab world." - The Australian
