Leaders of the Jersey City-based Muslim Federation of New Jersey condemned the mass shooting in Orlando and called the gunman a "self-proclaimed Muslim."

JERSEY CITY -- The Muslim Federation of New Jersey has condemned the mass shooting that killed 49 people inside an Orlando night club, and called the shooter a "self-proclaimed Muslim" who "clearly knows nothing about his faith."

"We as a Muslim community are extremely heartbroken by the news coming out of Orlando," Imam Saifun Nabi said this afternoon. "Our thoughts and prayers are with the victims in all our religious congregations since hearing the news."

The early morning massacre inside a gay nightclub is the deadliest mass shooting in U.S. history. The gunman, 29-year-old Omar Mateen, is alleged to have called a 911 operator to pledge allegiance to the Islamic State.

"We stand against any and all acts of violence and terrorism, especially those that target people simply for being who they are," Nabi said.

When asked during an interview in the backroom of the Montgomery Street mosque why the Muslim Federation feels the need to publicly denounce the shooting, Nabi said he feels Islamic communities are not given enough opportunity to show their religion is based on peace.

"The (shooting) is not only against every religion -- what he did -- but also it's against the laws of humanity. It never allows anyone to just go out and kill," he said.

Meanwhile, Presumptive Republican presidential nominee candidate Donald Trump this afternoon renewed his call to clamp down on Muslims immigrating to the United States. He said "radical Islam is coming to our shores" and vowed to temporarily band immigration from countries that have "a proven history of terrorism against the U.S., Europe or our allies."

However, the local group refused to even address the Trump's comments, saying they wish to not be associated with the businessman.

The horrific shooting comes during Ramadan, the holy month when Muslims fast from sunrise to sunset to be brought closer to their faith and remember the less fortunate. The Muslim Federation decorates its building with lights during the religious observation, however, the lights will be kept off for the next three days to show solidarity with the LGBT community.

Leaving the building, one woman stopped to say Muslims are "peaceful people" and don't "do those things," referring to the shooting in Orlando.

Jersey City will hold a vigil for the victims of the shooting at 8 p.m. Tuesday night at the Newark Pedestrian Plaza.
