Ibn Rajab al-Hanbali

Zayn ad-Din Abdurrahman ibn Ahmad ibn Rajab al-Hanbali (736-795 AH / 1335-1393 CE) was a major Hanbali scholar, hadith master, and author of some of the most treasured works in Islamic devotional and legal literature. Born in Baghdad, he moved to Damascus as a child and studied under the leading Hanbali and hadith scholars of the Levant and Egypt, most notably Ibn al-Qayyim al-Jawziyyah (whom he met as a young student), Zayn ad-Din al-Iraqi, and many others.

Ibn Rajab's most famous work is Jami al-Ulum wal-Hikam (Compendium of Knowledge and Wisdom), a commentary on an-Nawawi's Forty Hadith plus eight additional hadith. This work goes far beyond a simple hadith commentary, providing for each narration a thorough discussion of its chains of transmission, variant wordings, legal implications, spiritual lessons, and the positions of the four schools. It is one of the most comprehensive single-volume works combining hadith with fiqh and spiritual insight. He also authored Lata'if al-Maarif (on the seasonal acts of worship throughout the Islamic year), Fath al-Bari (a commentary on Sahih al-Bukhari that he left incomplete, covering up to the Book of Funeral Prayers), and adh-Dhayl ala Tabaqat al-Hanabilah (a continuation of the Hanbali biographical dictionary).

Ibn Rajab was known for combining deep legal and hadith scholarship with profound spiritual reflection. His writings beautifully blend the outward and inward dimensions of Islam. He died in Damascus in 795 AH (1393 CE). His works, particularly Jami al-Ulum wal-Hikam and Lata'if al-Maarif, are among the most beloved and widely read Islamic texts across all schools.
