Presented to the reader is the book al-Furqaan bayna Awliyaa ar-Rahmaan wa awliyaa ash-Shaytaan at a time in which Shaytaan has overcome the majority of mankind and knowledge of the differences between the Awliyaa of the Most Merciful and the awliyaa of Shaytaan is seldom found. In it, the author explained, in detail, the most important differences between the two categories of awliyaa, tackling the subject from various different angles and thoroughly refuting those who have gone astray in this matter. He discussed the issue of miracles and furnished the principles he laid out with examples of miracles performed by both groups of the awliyaa. Furthermore, he clarified some of the most important aspects of the Muslim belief, in all of this depending entirely upon the Book, Sunnah and understanding of the Salaf. May Allah have mercy upon him and reward him well.
