Manners in Speech

An oath is an oath At the outset of the Battle of Hunayn, the Muslims were forced back, leaving the Prophet and a few others to hold their ground. The Prophet called for the others to join him, but his voice was drowned by the din of battle. He turned, therefore, to Abbas, who had a voice of exceptional power and told him to shout: “O companions of the Tree1! O Companions of the Acacia!” to remind them of their oath of allegiance to the Prophet to fight unto death. Immediately the summons was answered from all sides-” Labbayk!” (“Here at your service!”) as Emigrants and Helpers rallied to his side. Abbas later recalled that they ran to the Prophet as calves run to their mothers. (MUSLIM, SAHIH)
