A book in English confirms that Allah - the Most-High - preserved Islam by preserving its two sources, the Quran and the Sunnah. To make this preservation perfect, we have to warn against the deviating sects and misguiding people that divided this nation, neglected the Prophetic tradition, and deliberately added heresies to Islam. The writer says in his introduction: This compilation was adapted from the third section of Ph.D thesis published under the title, "Wasatiyyah ahl Sunnah bayna al Firaq" which means "Moderation of Ahl- Sunnah between the Sects" written by Dr. Muhammad Ba’kareem Muhammad Ba’Abdullah, a professor in the Islamic University of Medina, KSA.
