According to data from the Pew Research Center, the creed breakdown of Muslims in the Somali-majority Djibouti is as follows: 77% adhere to Sunnism, 8% are non-denominational Muslim, 2% are Shia and 13% declined to answer, and a further report inclusive of Somali Region stipulating 2% adherence to a minority sect (e.g. Ibadism, Quranism etc.). There are some nobles who believe with great pride that they are of Arabian ancestry, and trace their stirp to Muhammad's lineage of Quraysh and those of his companions. Although they do not consider themselves culturally Arabs, except for the shared religion, their presumed noble Arabian origins genealogically unite them. The purpose behind claiming genealogical traditions of descent from the Arabian Peninsula is used to reinforce one's lineage and the various associated patriarchs with the spread of Islam.
