عمار بن ياسر
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.
