Banū ‘Abd ad-Dār (Arabic: بنو عبد الدار, "Sons of the Servant of the House"—referring to the Kaaba) is a sub-clan of the Arab Quraysh tribe.
Their progenitor is Abd-al-Dar ibn Qusai ibn Kilab. Historically, this tribe carried the banner in war, and Muhammad continued that tradition. In battles between the Makkans and the Muslims, the banner was frequently carried on both sides by a member of this tribe. Known to be the custodian of the Kaaba during pre-Islamic and upheld by the Prophet later on.
