Minhaj Ahl al-Haqq wal Ittiba' fi Mukhalafa Ahl al-Jahl wal Ibtida' - Ibn Sahman

The Way of the People of Truth and Following in their opposition to the People of Ignorance and Innovation, is a risala written by the great scholar of Najd, Shaykh Sulayman ibn Sahman (1266-1349H).

It mainly deals with the conflict between the people of the Sunnah and the Khawarij in issues of Takfir. But there's really a lot of interesting points that are discussed.

The book is authenticated by Sheikh Abdessalam ibn Barjas.
