This report (I can't assess its credibility because I don't know the publication) contains references to funding of Fath-Al-Islam from Bahiyyah Al-Hariri, and to links between the organization and Al-Qa`idah. This should not be surprising: many Bin Ladenites groups in Lebanon receive funding from Hariri Inc. The Hariri-funded Mufti of Biqa`, Khaldun Al-Mays, has been a Bin Laden advocates for years, and was reportedly one of the most enthusiastic recruiters of fighters for Al-Qa`idah in Iraq.
