The Museum reopened on September 2, 2021. The Museum’s mission is to inspire children to care about and change the world. The Museum received a U.S. Congressional designation in 2003 when Congress identified a need for a nationally recognized cultural and educational institution specifically for children.

The 1977 Hanafi Siege occurred on March 9–11, 1977 when three buildings in Washington, D.C. were seized by 12 Hanafi Movement gunmen. The gunmen were led by Hamaas Abdul Khaalis, who wanted to bring attention to the murder of his family in 1973. They took 149 hostages. After a 39-hour standoff, the gunmen surrendered and all remaining hostages were released from the District Building (the city hall; now called the John A. Wilson Building), B'nai B'rith headquarters, and the Islamic Center of Washington. The gunmen killed 24-year-old Maurice Williams, a radio reporter from WHUR-FM, who stepped off a fifth-floor elevator into the crisis (the fifth floor is where the mayor and Council Chairmen have their offices). The gunmen also shot D.C. Protective Service Division police officer Mack Cantrell, who died in the hospital a few days later of a heart attack. Then-Councilman and future 4-term Washington, D.C. Mayor Marion Barry walked into the hallway after hearing a commotion and was hit by a ricocheted shotgun pellet, which lodged just above his heart. He was taken out through a window and rushed to a hospital. The gunmen had several demands. They wanted the government to hand over a group of men who had been convicted of killing seven relatives – mostly children – of takeover leader Hamaas Khaalis. They wanted those that were convicted of killing Malcolm X. They also demanded that the premiere of Mohammad, Messenger of God be canceled and the film destroyed because they considered it sacrilegious.Time magazine noted: That the toll was not higher was in part a tribute to the primary tactic U.S. law enforcement officials are now using to thwart terrorists—patience. But most of all, perhaps, it was due to the courageous intervention of three Muslim ambassadors, Egypt's Ashraf Ghorbal, Pakistan's Sahabzada Yaqub-Khan and Iran's Ardeshir Zahedi.
