Salafists in Yemen published a book to criticize the Houthi rebels, revealing their opinion on the war waged against them, Al Bawaba News reported Wednesday. The book included Sheikh Yahya Alhajori's fatwa about the need to fight the Houthis as they attack Salafists, calling them infidels. Salafi scholars described the Shiite Houthis as infidels because they insult Al Sahaba (Prophet Mohamed's companions) and allow Nikah al Mutʿah (marriage for pleasure). The Salafists urged the Yemeni people to stop sympathizing with the Houthis as they massacre Sunnis, oppose the Quran and the Sunnah and kill Imams in Yemen.
