Sayyid Qutb has been associated with the religious ideology behind the radical sunni muslim groups such as al-Qaeda. It is known that Osama bin Laden was a inspired by many of the concepts – especially the idea of “Offensive Jihad” – brought forward in Sayyid Qutb’s most famous book Milestones. Here Qutb takes a twist on an originally spiritual concept, Jihad, describing mans “religious struggle” or “striving in the way of God“, and explains why this must be understood as the need of religious war against unbelievers. The story of Sayyid Qutb is really interesting, you might want to learn more about his years i the United States and how it formed his views (a drunk american woman tried to seduce him on the ship there :-). There is an excellent wikipedia entry here on his life: http://islamiclab.blogspot.com/2012/11/sayyid-qutb.html Here I have chosen to present Sayyid Qutb’s insanely huge work: In The Shade Of The Qur’an. The book is a well-written modern commentary to the entire content of the Qur´an and it is considered one of the most comprehensive and far-reaching. Each book is about 400 pages, I could not find the volumes 15-17, but I am sure you have hours of reading pleasure with these.
