[11] Despite a public announcement of his departure, it was alleged in a legal complaint filed against the promotion and its new owner, MMAX Investment Partners (doing business as PFL), that the organization "continued to use Abdelaziz throughout 2016".
While in jail, he was recruited by the New York Police Department's Deputy Commissioner of Intelligence, David Cohen, to work undercover within a Virginia-based arm of a group called Muslims of America.
The FBI eventually began to suspect he was operating as a double agent, having told people in Egypt of his life, particularly after he was reportedly administered a polygraph examination.
[14][15] This information was publicized in the book Enemies Within, written by American journalists Adam Goldman and Matt Apuzzo, and was used by Conor McGregor in an attempt to antagonise Abdelaziz at the UFC 229 press conference.
[14] Abdelaziz's time as an informant was also documented in the book Twilight in America, written by Christian Action Network founder Martin Mawyer and Patti Pierucci.
In the book, Abdelaziz spoke of his 8 years of experience gathering information about The Muslims of the Americas, a group founded in 1980 by Sheikh Mubarak Ali Gilani, allegedly connected with the terrorist organization, Jamaat ul-Fuqra.
