"Fi Zilal al-Qur'an" () is a highly influential commentary of the Qur'an, written during 1951-1965 by the Egyptian Sayyid Qutb (1906-1966), a leader within the Muslim Brotherhood. He wrote (or re-wrote) most of the original 30 volumes (114 Surahs) while in prison following an attempted assassination of Egyptian dictator Gamal Abdel Nasser in 1954. The book outlines Qutb's vision of a Muslim state and society. It is considered by some to be a comprehensive and far-reaching commentary that takes a clear and interpretation of the Qur'an. It has much influence throughout the Muslim world, especially amongst the ordinary lay practitioners of Islam in the Arab world.
