What the source says
Referenced, awaiting primary-source reviewAdopted on 7 September 1961. A horizontal triband of green, white and red; with a black trapezium based on the hoist side. The meanings derive from a poem by Safi al-Din al-Hilli: White are our deeds / Black are our battles / Green are our lands / Red are our swords. Red symbolizes the blood on the swords of Muslim warriors; white purity and noble deeds; black the defeat of enemies in battle.
