text: Abdullah Yusuf Azzam () was an Arab Islamist , jihadist and theologian from the Jordanian occupied West Bank. Belonging to the Salafi movement within Sunni Islam, he and his family fled from what had been the Jordanian-annexed West Bank after the 1967 Arab–Israeli War and pursued higher education in Jordan and Egypt before relocating to Saudi Arabia. In 1979, Azzam issued a fatwa advocating for "defensive jihad" in light of the outbreak of the Soviet–Afghan War, and subsequently moved to Pakistan to support the Afghan mujahideen.
  As a teacher and mentor to Saudi militant Osama bin Laden, he was one of the key figures who persuaded bin Laden to go to Afghanistan and personally oversee the mujahideen's efforts in that country. In 1984, Azzam and bin Laden co-founded Maktab al-Khidamat, an Islamic advocacy organization that sought to raise funds for the mujahideen while also recruiting non-Afghan fighters (known as Afghan Arabs) for their cause. Following the Soviet withdrawal from Afghanistan in 1989, he continued to promote jihadist militancy on behalf of other Muslims in other countries in an effort that led to him becoming known as the "father of global jihad" in many circles.
  On 24 November 1989, Azzam was killed by a car bomb detonated by unknown assailants in Peshawar, Pakistan.
