Bay'at al-Ridwan (Pledge Under the Tree)

During the Hudaybiyyah negotiations, a rumor spread that the Quraysh had killed the Muslim envoy Uthman ibn Affan. The Prophet sat beneath an acacia tree and called for a pledge to fight. All 1,400 companions pledged, and the Prophet placed his own hand over his other representing Uthman's pledge. Allah was pleased with them: 'Certainly Allah was pleased with the believers when they pledged allegiance to you under the tree' (48:18). The rumor proved false and negotiations resumed.
