العرب قبل الإسلام
A system of clan protection existed in Pre-Islamic Arabia, and people without a clan would stand without protection. Such a person could request for "Istijarah" (asylum) from a person already having a clan association in order to receive protection from that person. This was a common practice in Arabia, this was used by some Muslims who returned from the first Migration to Abyssinia, and Muhammad himself requested "Istijarah" from Mut'im ibn Adi after his return to Mecca from the visit to Ta'if. The term is also used in the Qur'an.
