Al-Zawahiri, the son of an upper middle-class family who had grown up in Al-Maadi, an affluent Cairene suburb, joined the Muslim Brotherhood at the age of fifteen right after the 1967 defeat. He quickly moved from the Brotherhood's ordinary ranks to join (and create) independent, highly radicalized cells. Though he had no links to the murder of Sadat, he was imprisoned in the major incarceration waves that followed the crime, and was sentenced to three years. Having served his prison sentence, he emigrated to Saudi Arabia, then soon afterwards to Afghanistan to join in the fight against the Soviets. It was during that time that he met Dr Abdullah Azzam, the Palestinian godfather of many militant Islamic groups and the founder of the Jihad Service Bureau, the vehicle that helped recruit thousands of Arabs to the Afghanistan War. Al-Zawahiri became a close friend and confidant of Azzam. After the Soviets' withdrawal from Afghanistan, he returned to Egypt where he became the effective leader of the Al-Jihad group. In 1992, Dr Al-Zawahiri joined his old Arab Afghan colleague, the Saudi multi-millionaire Osama bin Laden, in Sudan, and from there he continued to lead Al-Jihad, until its merger with Al-Qaeda in 1998. Dr Al-Zawahiri presented his thinking and rationale for ‘jihad by all means’ in his book Knights under the Prophet's Banner.38
