The opening as it read in 2010

Mosab Hassan Yousef ( Arabic : مصعب حسن يوسف; now known as Joseph ; born 1978 (age 47–48)) is a Palestinian and son of a Hamas founder and leader who spied for Israel from 1997 to 2007.1 Israel's internal security service, Shin Bet , considered Yousef the most valuable source within the Hamas leadership.2 The information Yousef supplied prevented dozens of suicide attacks , the assassination of Israelis, and exposed numerous terrorist groups. Yousef has since converted to Christianity and moved to California, in the United States. In March 2010, he published his autobiography, Son of Hamas: A Gripping Account of Terror, Betrayal, Political Intrigue, and Unthinkable Choices .3 His request for political asylum in the United States was granted pending a routine background check on June 30, 2010.4
