Nuh Ha Mim Keller (born 1954) is an Islamic scholar, teacher and author who lives in Amman. He is a translator of a number of Islamic books, a specialist in Islamic law, as well as being authorised by Abd al-Rahman al-Shaghouri as a Sheikh in the Shadhili Order.

Keller studied philosophy and Arabic at the University of Chicago and the University of California, Los Angeles. Keller converted to Islam from Roman Catholicism in 1977. He has cited Islamic philosopher Seyyed Hossein Nasr’s writings as one of the reasons for his conversion to Islam.

He then began a prolonged study of the Islamic sciences with prominent scholars in Syria and Jordan and was authorized as a shaykh in 1996.

He joined the Shadhili Sufi order, becoming a disciple of the Sufi poet Sheikh ʿAbd al‑Rahman al‑Shaghouri of Damascus (from whom he received his authorization) from 1982 until Shaghouri’s death in 2004.

His English translation of Umdat al‑Salik, Reliance of the Traveller (Sunna Books, 1991) is a Shafiʿi manual of Shariah. It is the first Islamic legal work in a European language to receive the certification of Al‑Azhar University.

Keller released a translation of the Quran titled The Quran Beheld in 2022, which strives to provide readers with a unique sense of the high eloquence and beauty of the Quran while also maintaining linguistic and rhetorical accuracy. In the translator’s own words, “Seven key areas of meaning” were “neglected by previous translations. Such gaps result in crucial elements of the Quran’s themes, logic, arguments, message, and meanings being lost. The Quran Beheld thus uncovers matters of Arabic meaning in the Quran for the first time in English.”

Keller has also written numerous articles and was a regular contributor to Islamica Magazine and the website masud.co.uk.

Currently, Keller lives in Amman, Jordan, where he established a zawiya (seminary) in the early 2000s. At its height, the community attending the institution is believed to have amounted to around 60 families living permanently in Jordan, along with hundreds of students of knowledge and families who visited for short stays seeking Keller’s spiritual insights as well as formal Islamic studies with scholars in the area.
