Ayn al-Qudat al-Hamadhani

Ayn al-Qudat al-Hamadhani (full name given variously in the sources as Abu'l-Ma'ali 'Abd Allah b. Abi Bakr Muhammad al-Miyanaji, or with the personal name Muhammad; the precise form is not settled) was a Persian Sufi (Islamic mystic) writer, jurist, and philosopher of the early 12th century. He came from a family of judges (qadis) in Hamadhan, in western Persia (modern Iran)—his grandfather and father are reported to have been well-known judges there—and his ancestral line is traced to Miyana, a town in the Tabriz region, which gives him the name al-Miyanaji. Reports describe a prodigious early education across Arabic, jurisprudence (fiqh), hadith, theology (kalam), and philosophy; some sources report that he studied mathematics and philosophy with the poet-mathematician Umar Khayyam, while others treat that link more cautiously.

He is associated with the Sufi master Ahmad al-Ghazali (younger brother of the famous theologian Abu Hamid al-Ghazali); sources differ on how close that bond was, ranging from 'came into contact with' to a full discipleship. He wrote in both Arabic and Persian. His best-known works are the Persian Tamhidat ("Paving the Path") and the Arabic Zubdat al-Haqa'iq ("Essence of the Realities"). Arrested on charges connected with heresy, he was imprisoned for a time in Baghdad, where he composed his Arabic Apologia, the Shakwa al-gharib ("The Exile's Complaint"). He was then taken back to Hamadhan and executed in 525/1131 by order of the Seljuq authorities, at roughly age 34.

Later Sufi tradition reveres him as one of Islam's celebrated "martyrs of love," alongside al-Hallaj; that devotional framing is a tradition held by his admirers rather than a neutral historical verdict, and the exact charges survive mainly through his own defense.
