His Eminence Sheikh Husein ibn Abdul-Aziz al-Sheikh, may Allah preserve him, delivered the Friday khutbah entitled, “The Importance Attached to Tawhid by the Prophet, Peace and Blessings be upon Him,” in which he talked about the advice of the Prophet, peace and blessings be upon him, to his Ummah, represented by his instructions to Abdullah ibn Abbas, may Allah be pleased with him and his father, in the well-known hadith. He highlighted some of the most important aspects of this advice, such as the emphasis laid by the Prophet, peace and blessings be upon him, on protecting tawhid (belief in the Oneness of Allah – true Islamic monotheism) and his fear that his Ummah might stray from the right path and fall into the abyss of polytheism. He cited some evidence to this effect from the Book of Allah and the Sunnah of His Prophet, peace and blessings be upon him.
