Ibn Rajab

Zayn al-Din Abd al-Rahman ibn Ahmad ibn Rajab was born in Baghdad and moved with his family to Damascus as a child. He studied under leading scholars in Syria, Jerusalem, and Egypt before settling in Damascus, where he taught at the Hanbali college and earned universal renown for his profound piety and ascetic humility.

Ibn Rajab authored monumental treatises on hadith commentary, ethical purification, and biographical history, including Dhayl Tabaqat al-Hanabila. His most celebrated work, Jami' al-Ulum wa-al-Hikam, is an exhaustive ethical and legal commentary on forty-two foundational prophetic maxims that remains a classic of Islamic spiritual literature.
