This is the english translation of the book: “An admonition to the God-fearing regarding the obligation of boycotting the people of innovation and desires”. This book is a complete guide to the manhaj of the Salaf when it comes to questions such as: ‘Who is the Sunnī, and who is the innovator?’, ‘How should we treat the innovator?’ and ‘How do we treat the one who does not disassociate from the innovator?’.
