Mujahideen allies: The Maktab al-Khidamat, also Maktab Khadamāt al-Mujāhidīn al-'Arab (Arabic: مكتب الخدمات or مكتب خدمات المجاهدين العرب, MAK), also known as the Afghan Services Bureau, was founded in 1984 by Abdullah Azzam, Wa'el Hamza Julaidan, Osama bin Laden and Ayman al-Zawahiri to raise funds and recruit foreign mujahideen for the war against the Soviets in Afghanistan.

As the war ended, a difference in opinion emerged between Azzam and the Egyptian Islamic Jihad (EIJ) led by Ayman al-Zawahiri over the future direction of MAK.

Al-Zawahiri wanted to use MAK's assets to fund a global jihad, including the overthrow of governments in Muslim countries deemed un-Islamic.

"[17] Most MAK financiers and support networks fronting as charitable NGOs were shut down and designated shortly following the September 11 attacks and the subsequent signing of the Patriot Act.

The Al Kifah Refugee Centre in Brooklyn, New York, established in the mid-to-late 1980s, was originally operated by Mustafa Shalabi, a close associate of MAK's co-founder Abdullah Azzam.

By 1988, Shalabi had set up with two chief aids inside the Al-Farooq Mosque, one of whom, Mahmud Abouhalima, would later be arrested for the 1993 World Trade Center bombing in New York.

that like Azzam, Shalabi had become embroiled in a power struggle with supporters of Bin Laden, namely Omar Abdel-Rahman (the Blind Sheikh) and his followers from the Al Farouq Mosque.

These tactics included, but were not limited to, dinner speeches and events at local mosques, donation "phonathons", open screenings of new Jihadist videos, a newsletter called "Al Hussam", and even university visits under the guise of Muslim Student Associations.

[20] Muntasser applied for and was granted a tax exemption from the IRS as a "non-political charity", enabling the organization to receive tax-exempt donations from around the United States.

Instead, the indictment alleges that some of the defendants engaged in financial transactions that benefited property controlled by a designated terrorist, in violation of the International Emergency Economic Powers Act".

[27] Founded in Saudi Arabia in the late 1980s as "Lajnat al-Birr al Islamiah" (LIB) by Sheik Adedl Abdul Galil Batterjee, the organization changed its name to Benevolence International Foundation (BIF) upon incorporating in Burbank Illinois, U.S.A in early 1992.
