Money problems proved costly to Bin Ladin in other ways. Jamal Ahmed al Fadl, a Sudanese-born Arab, had spent time in the United States and had been recruited for the Afghan war through the Farouq mosque in Brooklyn. He had joined al Qaeda and taken the oath of fealty to Bin Ladin, serving as one of his business agents. Then Bin Ladin discovered that Fadl had skimmed about $110,000, and he asked for restitution. Fadl resented receiving a salary of only $500 a month while some of the Egyptians in al Qaeda were given $1,200 a month. He defected and became a star informant for the United States. Also testifying about al Qaeda in a U.S. court was L’Houssaine Kherchtou, who told of breaking with Bin Ladin because of Bin Ladin’s professed inability to provide him with money when his wife needed a caesarian section.
