Personal life
Aboushi is the ninth of ten children born to Palestinian parents who immigrated to New York from Beit Hanina, a Palestinian neighborhood of East Jerusalem. Aboushi speaks English and some Arabic. He is also a practicing Muslim, one of few in the NFL. During Ramadan, which fell every year during training camp season at Virginia, he fasted from dawn to sunset every day. He was one of almost a dozen Muslim athletes honored by the U.S. Department of State for his contributions in 2011. He is one of the first Palestinian players in the NFL. On July 12, 2013, the Anti-Defamation League issued a press release defending Aboushi after an article circulating online claimed he was a 'Muslim extremist'. ADL defended Aboushi's right to take 'pride in his Palestinian heritage' and emphatically stated that being pro-Palestinian is in no way equivalent to being anti-Semitic or a Muslim extremist. In 2014 and 2015, Aboushi traveled to Sudan with the Islamic Medical Association of North America to help repair cleft lips and cleft palates in the impoverished East African nation. Working with the IMANA SaveSmile team, Aboushi helped to perform surgery that adjusted muscles and connected tissues allowing full lips to form in place of cleft palates.
