Abū Luʾluʾa Fīrūz—also known in some sources by his Middle Persian name Fīrūz—was a Persian captive, believed to have been brought from Nahavand or its vicinity, who assassinated the second caliph, ʿUmar ibn al‑Khattāb, in November 644 (26 Dhū al‑Ḥijja, 23 AH) (iranicaonline.org). He was a skilled artisan, proficient as a joiner and blacksmith, skills that apparently earned him exceptional access to Medina to work for the caliph despite restrictions on non-Arabs (iranicaonline.org).

Historical sources differ on Abū Luʾluʾa’s religion, describing him either as Zoroastrian (Mazdean) or Christian, and some later speculation of his conversion to Islam remains unverified (iranicaonline.org). The commonly cited motive is a dispute over a tax—or kharāj—that his Arab master, al‑Mughīra ibn Shuʿba, imposed on him; when ʿUmar refused to relieve this burden, Abū Luʾluʾa attacked during the congregational prayer (iranicaonline.org).

Accounts of the assassination vary: he concealed a double‑bladed dagger and struck while ʿUmar was praying—some accounts say he struck multiple worshippers—and in some versions the caliph died immediately, in others he lingered for up to three days (iranicaonline.org). The fate of Abū Luʾluʾa is also unclear, with some sources stating he was captured and executed, and others suggesting he committed suicide (iranicaonline.org).

In the aftermath, ʿUmar’s son, ʿUbayd Allāh ibn ʿUmar, retaliated by killing Abū Luʾluʾa’s daughter, Hormuzān—a former Sasanian officer—and a Christian man named Jufayna; this action was later judged by a tribunal, which ultimately released ʿUbayd Allāh after compensation was paid (en.wikipedia.org).

From the Safavid period onward, a shrine was built in Kashan, Iran—believed by some to be Abū Luʾluʾa’s burial place—and the festival known as Omar Koshan (“the killing of ʿUmar”) began to be celebrated annually at this site during the conversion of Iran to Shiʿism in the 16th century (en.wikipedia.org). Abū Luʾluʾa is affectionately referred to in this context as Bābā Shujāʿ al‑Dīn (“Father Courageous of the Faith”) (en.wikipedia.org). The shrine, dating architecturally from the Mongol era, was formally closed in 2007 under political and religious pressure (en.wikipedia.org).
