The first part of this book is a presentation of the thought and teachings of one of the leaders of original Sunni Sufism in the history of Islam. Imam Ahmad Al-Rifai holds fast to the Islamic law (Shariah) along with an understanding of the truth handed over to those who learnt from his path and followed it after him. This may differ from some of the malpractices of some of the contemporary associates of the Rifai sufi path. The second part of this book "Al-Burhaan Al-Mu'ayyad" , (The Advocated Proof) which is the most famous book of Imam Ahmad Al-Rifai, is about Sunni Islamic Sufism. It is a collection of sermons (lessons) delivered to his followers and students. It explains matters of spiritual purity and increasing closeness to God Almighty by worship, piety and decent manners, according to Islamic religion and the platforms of the Quran and prophetic teachings. It talks about gathering the hearts and souls through tolerance and restoring the right path by being repentant, humble and knowledgeable, according to the basis of the right of Islamic sufism in order to arrive to the gratification of God.
