The head of the Texas Chapter of American Muslims for Palestine, Suleiman is known for his long history of antisemitic comments. In 2017, he posted an image on social media in support of the Muslim Brotherhood. He has denied that Hamas uses civilians for human shields, taken the side of terrorist the Hamas terrorist organization repeatedly and said gays and lesbians were akin to people who engage in bestiality. During a 2012 lecture, Suleiman prayed for the “humiliation” of Israel and Jews who support it, stating “We ask Allah to humiliate this Israel, the way that Allah humiliated Beni Israel…We ask Allah to humiliate those who occupy the ‘land of Filastin [‘Palestine’].” In a speech that took place after the October 7 terror attack on Israeli civilians in 2023, Suleiman equated the phrase “I stand with Israel” with “a blank check for genocide.”
