or
ibn Abi Bakr) witnessing the purported conspiracy of Abu Lu'lu'a,
Hurmuzān, and Jufayna (wrongly depicted here as a woman; the depiction of the murder weapon may also be wrong) Very little is known about his life. According to some historical accounts, Abu Lu'lu'a was a
Zoroastrian from
Nahavand (Iran), though other reports describe him as a
Christian. A highly skilled
joiner and
blacksmith, Abu Lu'lu'a was probably taken captive by his Arab master
al-Mughira ibn Shu'ba in the
Battle of Nahavand (642) and subsequently brought to
Arabia, where he may also have converted to Islam. Other historical sources report that he was rather taken captive by al-Mughira in the
Battle of al-Qadisiyya (636), or that he was sold to al-Mughira by
Hurmuzān, an ex-
Sasanian military officer who had been working for Umar as an adviser after his own capture by the Muslims. Although
Medina was generally off-limits to non-
Arab captives under
Umar's reign, Abu Lu'lu'a was exceptionally allowed to enter the capital of the
early caliphate, being sent there by al-Mughira to serve the caliph. When al-Mughira forced Abu Lu'lu'a to pay a tax of two
dirhams a day, Abu Lu'lu'a turned to Umar to protest this tax. However, Umar refused to lift the tax, thus provoking Abu Lu'lu'a's rage. This is the reason given by most historical accounts for Abu Lu'lu'a's assassination of Umar, but Abu Lu'lu'a's true motivations are not clear. According to
Wilferd Madelung in his
The Succession to Muhammad, Umar's biased policies against non-Arabs may have played a prominent role in creating the climate which lead to the assassination. One day when Umar was leading the congregational prayer in the
mosque of Medina, Abu Lu'lu'a stabbed him with a double-bladed dagger. There are different versions of how this happened: according to one version, he also killed Kulayb ibn al-Bukayr al-Laythi who was behind Umar, while in another version he stabbed thirteen people who tried to restrain him. According to some accounts, the caliph died on the day of the stabbing (Wednesday of the , or according to the
Gregorian calendar), while other accounts maintain that he survived three more days. Some historical sources report that Abu Lu'lu'a was taken prisoner and executed for his assassination of Umar, while other sources claim that he committed suicide. After Abu Lu'lu'a's death, his daughter was killed by
Ubayd Allah ibn Umar, one of Umar's sons. Acting upon the claim of one man (either
Abd al-Rahman ibn Awf or
Abd al-Rahman ibn Abi Bakr) that they had been seen conspiring with Abu Lu'lu'a while he was holding the double-bladed dagger, Ubayd Allah also killed Hurmuzān (Umar's Persian military adviser), and Jufayna, a Christian man from
al-Hira (Iraq) who had been taken to Medina to serve as a private tutor to a family in Medina. After Ubayd Allah was detained for these murders, he threatened to kill all foreign captives residing in Medina, as well as some others. Although Ubayd Allah may have been encouraged by his sister
Hafsa bint Umar to avenge their father's death, his murder of Hurmuzān and Jufayna was likely the result of a mental breakdown rather than of a true conspiracy. It was regarded by his peers as a crime rather than as a legitimate act of retaliation. In early 20th-century scholarship it was sometimes supposed that Abu Lu'lu'a had really been an instrument in the hands of a conspiracy, though not a conspiracy led by Hurmuzān, but rather one led by
Ali,
al-Zubayr ibn al-Awwam, and
Talha ibn Ubayd Allah. These men, who according to the historical sources were appointed by Umar himself as members of the council who would elect the next caliph, were thought by scholars to have conspired to overthrow Umar's reign and to put Ali in his place. This hypothesis, however, is rejected by more recent scholars. Nevertheless, while Ubayd Allah was subsequently acquitted of his crimes by Umar's successor
Uthman (r. 644–656), who considered the execution of Ubayd Allah an excessive measure in view of his father's recent assassination, Ali, among others, did protest against this and vowed to apply the regular punishment for murder if he were ever to be caliph. Madelung in his
The Succession to Muhammad has pointed out that just like Abu Lu'lu'a's assassination of Umar over something as trivial as a tax burden, Ubayd Allah's retaliatory killing of apparently random non-Arabs bears witness to the strong tensions that existed between Arabs and non-Arabs in the early Islamic caliphate. According to Tayeb El-Hibri, the 9th-century historians who recorded these events (amongst others,
Ibn Sa'd,
al-Baladhuri,
al-Tabari) regarded them as laying the first seeds of the special affinity between Persia and the
Hashimid family of the prophet (including Ali), which would later be reflected in the crucial role played by
Khurasani converts in overthrowing the Umayyads and establishing the Hashimid rule of the
Abbasids during the
Abbasid Revolution (750 CE). ==Legacy==
