Essentials of Bid’ah forms the second and the third section of the book titled: Da’watu Ahl-Bid’ah (Inviting the People Of Innovations). In a very concise manner Shaykh Khalid bin Ahmad Az Zahraanee expounded on both the lexical and juristic meaning of the word Bid’ah, it’s evil effects and the words of disparagement, categories of Bid’ah, dealing with the people of Bid’ah, that has been mentioned in the Qur’an, the Sunnah of the Prophet, the statements and actions of the Companions and those who follow in their footsteps from the scholars over time regarding Bid’ah and its people.

The book proves the important, yet overlooked point: that despite whatever differences the Imaams had in their fiqh, their creed (aqidah) was one and the same in almost all issues. Many narrations are brought from the past and present day scholars showing that the path to Allaah is one. Detailed biographies have been provided for each of the four Imaams from ancient authentic sources. Additionally many doubts cast over the creed and lives of the Imaams have been uncovered, and the Creed of the Ahlus-Sunnah wal-Jama’ah has been exonerated.
