Banu Abd-al-dar (Arabic: بني عبدالدار, English: Sons of the Servant of the Mosque) is an Arabic sub-clan of the Quraish tribe.
Their progenitor is Abd-al-Dar ibn Qusai ibn Kilab.[1] 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.
