The videos were posted in mid-April to the Facebook page of the Muslim American Society's Islamic Center in Philadelphia. It showed children singing a range of violent lyrics, including: "The blood of the martyrs is calling us. Paradise, men desire it."
The Muslim American Society (MAS) said in a statement that the songs were not "properly vetted."

According to its website, the Muslim American Society has more than 50 chapters throughout the United States. Part of its mission is "to convey Islam with utmost clarity."
About 40 Brotherhood members from across the country gathered in 1993 to form the group, former member Mustafa Saied told the Tribune. But an internal document circulated by the society advised leaders who were asked if they were part of the brotherhood to respond that they were an independent group.
"And if the topic of terrorism were raised, leaders were told to say that they were against terrorism but that jihad was among a Muslim's 'divine legal rights' to be used to defend himself and his people and to spread Islam," the Tribune stated. Shaker Elsayed, a top official in the group at the time, said that about 45 percent of the most active members also belonged to the Muslim Brotherhood.

According to IRS filings, most of the money the group collects is aimed at schools, teachers, and children.
In its statement in response to the videos, the society claimed it was against all forms of hate.
“As a faith-based organization dedicated to moving people to strive for God-consciousness and a just and virtuous society, we affirm our long-standing position on our shared values of humanity. We stand resolutely in our condemnation of hate, bigotry, Islamophobia, xenophobia, racism, anti-Semitism and all the illnesses of hate that plague our society,” it stated.
"Our investigation revealed that the school that organized the event on April 17, 2019, is a separate entity renting space from MAS Philadelphia. The school board has informed us that it has taken immediate actions and dismissed the person in charge of the program. In addition, they will form a local commission to aid in sensitivity training and proper supervision for future programs," it stated.
Philadelphia's Anti-Defamation League was among the individuals and groups criticizing the event, calling it "extremely disturbing."
The Muslim American Society was declared a terrorist organization by the United Arab Emirates in 2014 in a list that also included ISIS, the Muslim Brotherhood, and Boko Haram.
According to the Investigative Project on Terrorism, events held by radical Muslims are more common than people realize. The group said that the group, American Muslims for Palestine (AMP), held a workshop entitled "Palestine Will Be Free" at a mosque associated with the Muslim American Society's Philadelphia chapter and at least five officials from AMP were linked to a now-defunct group that was tasked with helping the Hamas terrorist group both financially and politically.
"This mindset was on full display during the MAS-Philadelphia event, as children donned T-shirts with a map of Israel and the territories as a singular Palestinian entity. Denying Israel's right to exist is a form of anti-Semitism."
