On October 11, 2001, Newsday reported that "Saudi scholar Abdul Al-Mutairi asserts, 'In reality, Islam recognizes extremism as a disease.'" The article continues to report that "after the United States began its military attack... a tape emerged of bin Laden...in which he urged the Muslims to fight a "jihad" against Americans." The article's author Professor Ibrahim Negm explains that "in Islamic law, for a claim to be religiously credible, it has to echo two things: the Quran, the Muslim holy book, and the Sunnah, the sayings of the prophet Muhammad. Without these...it is tantamount to opinion based on one's personal interpretation. Bin Laden's statement is just that...bin Laden's use of the word jihad [also] represents how the whole notion of a "holy war" has become one of the most misunderstood and abused aspects of Islam."
