Injury During the Battle of Yamama
Hazrat Ibn Umar says, “I saw Hazrat Ammar (ra) in the battle of Yamama. He was standing on a high mound and was calling upon the Muslims. He was a very brave man. He said, ‘O Muslims! Are you running away from paradise? I am Ammar bin Yasir, come towards me.’” Hazrat Ibn Umar further states, “I was watching him and noticed that one of his ears was cut deeply and was dangling. Despite all of this, Hazrat Ammar was engrossed in the battle.”

In reference to the same injured ear, Tariq bin Shahab states, “Someone from the Banu Tamim tribe taunted Ammar (ra) about his mutilated ear. Hazrat Ammar (ra) responded by saying, ‘You have insulted my finest ear.’”

That is, you are mocking me for the ear that was sacrificed in a battle for the sake of God Almighty; this ear of mine is my best ear.
