Al-Qudwa was the name of his tribe and al-Husseini was that of the clan to which the al-Qudwas belonged. The al-Husseini clan was based in Gaza and is not related to the well-known al-Husayni clan of Jerusalem. Since Arafat was raised in Cairo, the tradition of dropping the Mohammed or Ahmad portion of one's first name was common; notable Egyptians such as Anwar Sadat and Hosni Mubarak did so. However, Arafat dropped Abdel Rahman and Abdel Raouf from his name as well. During the early 1950s, Arafat adopted the name Yasser, and in the early years of Arafat's guerrilla career, he assumed the nom de guerre of Abu Ammar. Both names are related to Ammar ibn Yasir, one of Muhammad's early companions. Although he dropped most of his inherited names, he retained Arafat due to its significance in Islam. Rise of Fatah Founding of Fatah Following the Suez Crisis in 1956, Egyptian president Gamal Abdel Nasser agreed to allow the United Nations Emergency Force to establish itself in the Sinai Peninsula and Gaza Strip, precipitating the expulsion of all guerrilla or "fedayeen" forces there—including Arafat. Arafat originally attempted to obtain a visa to Canada and later Saudi Arabia, but was unsuccessful in both attempts. In 1957, he applied for a visa to Kuwait (at the time a British protectorate) and was approved, based on his work in civil engineering. There he encountered two Palestinian friends: Salah Khalaf ("Abu Iyad") and Khalil al-Wazir ("Abu Jihad"), both official members of the Egyptian Muslim Brotherhood. Arafat had met Abu Iyad while attending Cairo University and Abu Jihad in Gaza. Both would later become Arafat's top aides. Abu Iyad traveled with Arafat to Kuwait in late 1960; Abu Jihad, also working as a teacher, had already been living there since 1959. After settling in Kuwait, Abu Iyad helped Arafat obtain a temporary job as a schoolteacher. As Arafat began to develop friendships with Palestinian refugees (some of whom he knew from his Cairo days), he and the others gradually founded the group that became known as Fatah. The exact date for the establishment of Fatah is unknown. In 1959, the group's existence was attested to in the pages of a Palestinian nationalist magazine, Filastununa Nida al-Hayat (Our Palestine, The Call of Life), which was written and edited by Abu Jihad. FaTaH is a reverse acronym of the Arabic name Harakat al-Tahrir al-Watani al-Filastini which
