The predominant Somali mosque, like many other mosques around the country, has received threatening calls and emails, Omar told the Star Tribune.
"It was 5 a.m. (0900GMT)," he said. "The whole neighborhood was calm. People were supposed to be sleeping, that's how peaceful this should be. I was shocked to learn this happened."
The Council on American Islamic Relations (CAIR), announced a $10,000 reward for information leading to the arrest and conviction of the attacker.
It's national office also urged mosques and Islamic centers nationwide to increase security.

"The incident is a symptom of the growing atmosphere of Islamophobia in the U.S," the group's communication director, Ibrahim Hooper, told Anadolu Agency. "Because whenever you look at what would be a possible motive in this kind of case, it seems that Islamophobia would be a main type of motivation that you would look at."
Hooper said rewards have been successful in the past to receive information leading to an arrest.
"Because often they brag to people and friends, their relatives, that they've done this and they are proud of it. Then somebody eventually, because of the incentive of the reward, offers information to the police and they are arrested," he added.
