Omar Regan, a comedian and son of Imam Luqman Ameen Abdullah of Detroit, led prayers Friday at a makeshift mosque after his father died in an F.B.I. raid.
DETROIT — Friday prayers were intoned on schedule at the red brick two-story house on the west side that is a makeshift home for the Masjid Al-Haqq mosque.
But leading the prayers was a son of the mosque’s imam, Luqman Ameen Abdullah, who was killed by federal agents in a raid on Wednesday. The son, Omar Regan, 36, a comedian and motivational speaker, flew from Los Angeles to mourn and defend his father, who was described in federal court papers as a separatist Muslim intent on overthrowing the United States government.
“My father was a sharp-tongued individual,” Mr. Regan said. “He would talk about his dislike of the government, about how law enforcement wasn’t protecting and serving the people. But speaking his emotions and acting on his emotions are two different things.”
Mr. Regan’s sentiments were echoed by many Muslims here and across the country on Thursday and Friday, as some leaders portrayed the Federal Bureau of Investigation’s counterterrorism squad of using heavy-handed tactics against Mr. Abdullah, who was not accused of terrorism.
Asked why Mr. Abdullah had not been charged with terrorism, the United States attorney for the Eastern District of Michigan, Terrence Berg, said, “The charges speak for themselves.”
Mr. Abdullah, 53, died in a shootout in the raid of a warehouse just outside the city, in Dearborn, where he stored goods. The raid was one of three in which federal agents said were intended to arrest Mr. Abdullah and 10 other men on charges that included conspiracy to sell stolen goods, mail fraud and illegal possession of firearms. But the authorities said Mr. Abdullah, who had a lengthy criminal record and was forbidden to have a firearm, opened fire on the agents.
He died of multiple gunshot wounds, said a spokesman for the Wayne County coroner.
“I’m comfortable with what our agents did,” said Andrew G. Arena, special agent in charge of the Detroit division of the F.B.I. “They did what they had to do to protect themselves.”
Two of the 11 defendants remain at large; one, Mujahid Carswell, 30, another son of Mr. Abdullah, was arrested Thursday in Canada. (Law enforcement officials said Mr. Abdullah’s shots killed an F.B.I. dog, Freddy, who is to be honored for dying in the line of duty, officials said.)
A 43-page criminal complaint described Mr. Abdullah as the belligerent leader of a faction of a group called the Ummah, meaning “the Brotherhood,” which advocates the establishment of a separate nation governed by Islamic laws within the United States. The authorities had been monitoring him for years.
In January, city officials evicted Mr. Abdullah’s mosque, which counts about 25 families as members, from its original location for failure to pay property taxes. He relocated to the two-story home on the west side. During the eviction, the police said, officers found two guns and about 40 other weapons in Mr. Abdullah’s apartment.
Law enforcement officials said they were concerned about retaliation in the wake of Mr. Abdullah’s death.
But the federal complaint on which Wednesday’s raid was based also shows how much trouble Mr. Abdullah and his associates had in executing even basic criminal schemes, like switching the vehicle identification numbers on a stolen truck, or selling stolen laptops. While full of bravado, they are characterized in the complaint as being a far cry from masterminds, a notion that some of Mr. Abdullah’s acquaintances supported.
“They knew a long time ago that this was a penny ante operation, and they could have stopped it,” Abdullah El-Amin, an imam at the Muslim Center, Detroit’s largest black mosque, said of federal authorities. “It didn’t have to get to this point, people getting killed.”
Mr. El-Amin said he had known Mr. Abdullah for more than 20 years, although they had never attended the same mosque. Mr. El-Amin said he had heard Mr. Abdullah talk about wanting a separate state, but described it as “sort of like the Pennsylvania Dutch have their own communities and stuff.” Some, but not all, mainstream Muslim leaders agreed that Mr. Abdullah had held that view.
“The very incendiary rhetoric that the F.B.I. alleges, I never heard that from him,” said Dawud Walid, executive director of the Michigan chapter of the Council on American-Islamic Relations. “There was nothing extraordinary about him.”
The Muslim Public Affairs Council, a policy and advocacy group based in Los Angeles, is calling for an investigation of Mr. Abdullah’s killing, which it describes as “deeply disturbing.”
But Eide A. Alawan, director of the office of interfaith outreach at the Islamic Center of America, one of the largest Muslim centers in the Midwest, in Dearborn, took a critical view of Mr. Abdullah and his defenders.
“This is not the first time in history that someone has used a religion to do some harm in the name of faith,” Mr. Alawan said. “Now is an opportune time for some to show their militancy. It gets attention. But it’s no different than the Ku Klux Klan in the 40s and 50s using the cross.”
The Muslim Alliance in North America, a national network based in Lexington, Ky., expressed shock at the killing of Mr. Abdullah, who served on its governing body.
“Reference to the Ummah as a ‘nationwide radical fundamentalist Sunni group consisting primarily of African-Americans’ is an offensive mischaracterization,” the group said in a statement.
“To those who have worked with Imam Luqman A. Abdullah,” it continued, “allegations of illegal activity, resisting arrest, and ‘offensive jihad against the American government’ are shocking and inconsistent. In his ministry he consistently advocated for the downtrodden and always spoke about the importance of connecting with the needs of the poor.”
A funeral for Mr. Abdullah is scheduled for Saturday at the Muslim Center in Detroit.
