Singling out Allah His Ruboobiyyah (Lordship), Uloohiyyah (regarding worship) and His Asmaa was-Sifaat (Names and Attributes) forms the mainstay of the subject of Tawheed. Kitaab at-Tawheed by Shaykh al-Islam, Muhammad bin Abdil-Wahhaab bin Sulaymaan at-Tameemee, covers the various broader aspects of Tawheed. What it means, the stipulations of the Qur'an and the Sunnah for the individual's Tawheed to be sound. The Mighty and Sublime matters that contradict a person's Tawheed rendering it null and void, and those that only affect its strength, causing it to be weak and feeble. In his usual, clear, investigative, analytic approach, the eminent scholar, Ash-Shaykh, al-'Allaamah, Muhammad bin Saalih al-'Uthaymeen explained Kitaab at-Tawheed. Titled al-Qawl al-Mufeed 'alaa Kitaab at-Tawheed, Shaykh Ibn al-Uthaymeen's commentary is replete with tremendous knowledge-based benefits not only about the issues of Tawheed but also regarding other matters of creed, worship, Fiqh and its Usool, noble character and manners and other aspects of the Islamic sciences packaged in unique grammatical expressions.
