Sayyid Ibrahim Husayn Shadhili Qutb (9 October 1906 – 29 August 1966) was an Egyptian political theorist and revolutionary who was a leading member of the Muslim Brotherhood.
As the author of 24 published books, with around 30 unpublished for different reasons (mainly destruction by the state), and at least 581 articles, including novels, literary arts critique and works on education, Qutb is best known in the Muslim world for his work on what he believed to be the social and political role of Islam, particularly in his books Social Justice and Ma'alim fi al-Tariq (Milestones). His magnum opus, Fi Zilal al-Qur'an (In the Shade of the Qur'an), is a 30-volume commentary on the Quran. Even though most of his observations and criticism were leveled at the Muslim world, Qutb also intensely disapproved of the society and culture of the United States, which he saw as materialistic, and obsessed with violence and sexual pleasures.He advocated violent, offensive jihad.
