[1] The Nussaiba family has a long history and tight bonds with the Holy Land, and the Christian people of the Levant, since the days their first forefathers conquered Jerusalem in the 7th century.
The Nusseibeh family is historically and genealogically linked to Ubadah ibn al-Samit, a prominent companion of the Prophet Muhammad, from the Khazraj tribe of Medina.
While Nusaybah bint Ka'ab (Umm Umarah), an esteemed female companion of the Prophet known for her bravery in battle, is sometimes mentioned in relation to the family, this association is more symbolic than genealogical.
[3][4][5][6] This arrangement emerged during the days of the second caliph Umar Ibn al-Khattab, who hoped to avoid clashes among rival Christian sects for control over the church.
The ancient records and manuscripts kept by the various Christian denominations in their monasteries all record the Nussaiba family’s relationship and that of their ancestral forefathers from the Bani Ghanim al-Khazraj to the Holy Sepulchre, at least since the time of Saladin more than 800 years ago, specifically since 1192, when Sultan Saladin and King Richard the Lionheart concluded an agreement allowing western Christian pilgrims to visit the Holy Sepulchre under certain stipulations.
