According to law enforcement officials, Jamiyyat Ul Islam Is Saheeh is a radical Islamist prison gang, adhering to the philosophy of the Prophet Muhammad. The gang is also known as the "Assembly of Authentic Islam." The organization has been accused of putting forward a protocol by leader James meant to justify attacks on enemies of the Islamic faith, the U.S. government, Jews, Israel-supporters, and "infidels." Operations allegedly include robbing gas stations to raise start-up money for terrorist attacks.

Jamiyyat Ul Islam Is Saheeh is labeled as a Security Threat Group, not a gang. Even without supposed ties to professional terrorist organizations, the Assembly of Authentic Islam was accused of hatching a complex terrorist plot from within prison walls, according to an FBI affidavit.

Lamar James was accused of directing his protoge Levar Haney Washington to find "clean" recruits without serious convictions, obtain weapons and appoint followers to educate them on explosives, bomb-making, or more recruitment. They were indicted in 2005 after allegedly being found with addresses of potential terrorism targets in Los Angeles, including National Guard facilities, the Israeli Consulate, and 2 synagogues.
