In the Battle of Khyber, which Jewish warrior was killed by Hazrat Ali (RA)? 

1. Marhab bin Al-Harith
2. Harith Abu Zaynab
3. Haris ibn Maslamah
4. Ja’far

The Jewish strongman Marhab fell to Hazrat Ali’s (RA) sword during the 629 CE siege of Khyber’s impregnable forts. According to “Maghazi” by al-Waqidi, Marhab wore layered armor and brandished a legendary sword when Ali (RA) engaged him near Fort Qamoos. Their poetic exchange before combat became proverbial in Arabic literature. Ali’s (RA) victory marked a turning point, leading to Khaybar’s surrender. Modern archaeological work at Khaybar has identified the probable location of this duel near the ancient Qamoos fortress ruins in Saudi Arabia’s volcanic highlands.
