Al-Naḍr ibn al-Ḥārith ibn ʿAlqama ibn Kalada ibn ʿAbd Manāf ibn Abd al-Dār ibn Quṣayy (Arabic: النضر إبن الحارث, d. 624 CE) was an Arab pagan physician who is considered one of the greatest Qurayshi opponents to the Islamic prophet Muhammad. He was captured after the Battle of Badr as one of the pagan fighters and flag-bearers. He was sentenced to death for his participation and persecution of Muhammed and Muslims in Mecca.[1] The execution was conducted by Ali by beheading him in front of Muhammad and his companions at as-Safra' before they had returned to Medina from the battle.
According to the Sīrah, two captives, al-Naḍr ibn al-Ḥārith and ʿUqbah ibn Abī Muʿayṭ, were executed during this event, the former by Ali and the latter by Asim ibn Thabit. According to Professor Sarah Bowen Savant, the event is claimed to have inspired Nadr's sister, Qutayla ukht al-Nadr, to compose an elegy on his death, upbraiding Muhammad for the execution.[2]
