Battle of Khaybar
Originally a Christian priest, al-Dari lived in Palestine and belonged to the Banu al-Dar—a clan of the Lakhm tribe. His first contact with Muhammad was in 628 CE when he led a delegation of ten other Banu al-Dar members. Previously Muhammad granted Banu al-Dar a part of the revenues of conquered land after the Muslim victory at the Battle of Khaybar. Al-Dari met with Muhammad to receive the revenues and after meeting him, al-Dari embraced Islam and settled in Medina.
