A Syrian imam who endorsed Palestinian suicide bombings and was banned from Denmark last year as a “hate preacher,” is now visiting several mosques in the eastern United States.

“All the Jewish people are combatants,” meaning they are acceptable targets for attacks, Sheikh Mohammed Rateb Nabulsi wrote in his 2001 “ruling on martyrdom operations in Palestine.”

“They do not have a career that a military rank does not encounter: doctor, pilot, engineer, for example, is a tank commander. Every civilian, citizen,” he wrote. “They do not have a regular army; they have a reserve army, and all the people can fight, so this is essentially an entirely aggressive entity from A to Z. This is the Sharia ruling.”

He deleted this fatwa from his Arabic website in 2014 after the Investigative Project on Terrorism (IPT) first wrote about his visit to the US on behalf of the Syrian American Council (SAC) and Shaam Relief. A cache of the original post remains available.

Nabulsi, who has endorsed the death penalty for homosexuals, also suggested in a 2010 post on his website that same-sex marriage was a reason for Muslims to wage violent jihad against the West.

Nabulsi spoke on Monday at the Dar al-Hijrah Islamic Center in Falls Church, Virginia, and last week at a middle school near Orlando and the Islamic Center of Boca Raton. He was scheduled to speak at the Islamic Society of Boston Cultural Center (ISBCC) on Wednesday, Masjid al-Farooq in Brooklyn on Thursday, the Islamic Center of Passaic County (ICPC) on Friday, and Saturday at the Bergen County Islamic Center.

His fundraising tour benefits the Rahma Relief Foundation and Mercy Without Limits, both charities that say they aim to help Syrian refugees.

Mercy Without Limits chairman and President Mohamad Albadawi also serves as a trustee of the Muslim American Society (MAS), which prosecutors say was founded as the “overt arm” of the Muslim Brotherhood in America. He was also listed in 1997 as the registered agent of the Muslim Arab Youth Association (MAYA), and his Mercy Without Limits biography says that he served as executive director. MAYA hosted Osama Bin Laden’s mentor Abdullah Azzam in 1989 and Muslim Brotherhood ideologue Sheikh Yusuf Qaradawi in 1995. Albadawi spoke at MAYA’s 1993 convention in Detroit.

The MAS hosted Nabulsi at its December 2016 convention in Chicago and he met that same month with senior Hamas leader Ismail Haniyeh in Qatar.

Zuhdi Jasser, a Syrian-American and founder and president of the American Islamic Forum for Democracy, condemned the mosques for treating Nabulsi as mainstream.

“It is incumbent upon every American Muslim, especially the Syrian community, to marginalize and defeat the ideas of radical Islamism peddled by the likes of Nabulsi,” Jasser said.
