Kitāb as-Sunnah al-Khallāl

Kitāb as-Sunnah is one of the most important foundational works on the authentic ʿAqīdah (creed) of the Salaf in the school of Imām Aḥmad ibn Ḥanbal. In it, Imām al-Khallāl meticulously compiles the statements, traditions, and legal positions of Imām Aḥmad and his early disciples on central questions of faith. The work provides a systematic and easily comprehensible insight into the original Hanbali doctrine—free from later theological innovations.

In a clear structure, it addresses topics such as the descriptions of Allah, the Iman and its components, the Qadar (divine decree), the position of the Sunnah, the treatment of the Jahmiyyah and other dissenting groups, as well as adherence to the transmitted texts without Ta'wil or Ta'til. Due to its extensive transmission of the text, this book is considered one of the most reliable sources for understanding the Salaf's methodology in the area of ​​Aqidah (Islamic creed) directly from original statements.

Kitāb as-Sunnah remains to this day an indispensable study work for all those who wish to learn about the pure, early Hanbali theology and base their knowledge on a firm foundation of authentic traditions.
