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.
