Born in Telafa, Iraq, Hassan Farhat (Arabic: حسن فرحات) (Abdul Jabbar, Abu Ossama, Abu Khalid) was the founder and Imam of Salaheddin Mosque in Scarborough, Toronto, Ontario, Canada.
However, he was made persona non grata by the worship centre's administration, and was allowed to return only for worship. After returning to Iraq in 2001, he was accused of being a "top Ansar commander" by the Patriotic Union of Kurdistan. Other sources have accused him of belonging to Egyptian Islamic Jihad.
After becoming a landed immigrant in Canada, Farhat lived on Eglinton East, but faced constant difficulty trying to obtain full citizenship, since Canadian Security Intelligence Service was wary of his connections to Egyptian Islamic Jihad.
In 1996, Farhat met Mahmoud Jaballah at the Medina Mosque in Toronto, and helped him find a local apartment and learn English. Farhat introduced Jaballah to Ali Hussein, and later moved to Winnipeg, Montreal and then back to Toronto. It was at his apartment in Montreal, following the birth of his child, that Jaballah and Mustafa Krer had their only Montreal meeting. Jaballah also visited him in Winnipeg, and phoned him 41 times, once telling him that Kassem Daher would appreciate any religious audiocassettes that Farhat and Jaballah could send him.
