Hazrat Abu Uqbah (may Allah be pleased with him) narrates that I participated in the Battle of Uhud with the Messenger of Allah (peace and blessings be upon him). I struck a polytheist with my sword saying, "Here, take this! I am a Persian slave." When the Messenger of Allah (peace and blessings be upon him) learned of this, he said, "Why did you not say that this blow is on my behalf? I am an Ansari slave."
