Al Qaeda
Al-Fadl was recruited to the Afghan mujahideen "through the Farouq mosque in Brooklyn" (presumably when he was in the U.S. in the mid 1980s), and he became a "senior employee" of al-Qaeda.
He attended two meetings from August 11–20 in 1988, along with Osama bin Laden, Ayman al-Zawahiri, Mohammed Atef, Mamdouh Mahmud Salim, Wael Hamza Julaidan, and Mohammed Loay Bayazid and eight others, to discuss the founding of "al-Qaeda". In Khartoum, he travelled to Hilat Koko with Mamdouh Mahmud Salim in late 1993 or early 1994, and met with Amin Abdel Marouf to discuss chemical weapons.
Fadl became a business agent for al Qaeda but resented receiving a salary of only $500 a month while some of the Egyptians in al Qaeda were given $1,200 a month. Osama bin Laden discovered that Fadl had skimmed about $110,000 and asked for restitution. Fadl then defected and became a star informant for the United States.
