youth activism as a student. He became both quite pious and political, under the influence of his uncle Mahfouz Azzam, and lecturer Mostafa Kamel Wasfi. Sayyid Qutb preached that to restore Islam and free Muslims, a vanguard of true Muslims modeling itself after the original Companions of the Prophet had to be developed. Ayman al-Zawahiri was influenced by Qutb's Manichaean views on Islamic theology and Islamic history. Underground cell By the age of 15, al-Zawahiri had formed an underground cell with the goal to overthrow the government and establish an Islamist state. The following year the Egyptian government executed Sayyid Qutb for conspiracy. Following the execution, al-Zawahiri, along with four other secondary school students, helped form an "underground cell devoted to overthrowing the government and establishing an Islamist state." It was at this early age that al-Zawahiri developed a mission in life, "to put Qutb's vision into action." His cell eventually merged with others to form al-Jihad or Egyptian Islamic Jihad. Marriages and children Ayman al-Zawahiri was married at least four times. His wives include Azza Ahmed Nowari and Umaima Hassan. In 1978, al-Zawahiri married his first wife, Azza Ahmed Nowari, a student at Cairo University who was studying philosophy. Their wedding, which was held at the Continental Hotel in Opera Square, was very conservative, with separate areas for both men and women, and no music, photographs, or gaiety in general. Many years later, when the United States attacked Afghanistan following the September 11 attacks in October 2001, Azza apparently had no idea that al-Zawahiri had supposedly been a jihadi emir (commander) for the last decade. Al-Zawahiri and his wife, Azza, had four daughters, Fatima (born 1981), Umayma (born 1983), Nabila (born 1986), and Khadiga (born 1987), and a son, Mohammed (also born in 1987; the twin brother of Khadiga), who was a "delicate, well-mannered boy" and "the pet of his older sisters," subject to teasing and bullying in a traditionally all-male environment, who preferred to "stay at home and help his mother." In 1997, ten years after the birth of Mohammed, Azza gave birth to their fifth daughter, Aisha, who had Down syndrome. In February 2004, Abu Zubaydah was waterboarded and subsequently stated that Abu Turab Al-Urduni had married one of al-Zawahiri's daughters. Ayman al-Zawahiri's first wife Azza and two of their six children, Mohammad and Aisha, were killed in an airstrike on Afghanistan by US forces in late
