Musa bin al-Harith al-Taymi narrates from his father: On the day of Badr, Hamzah bin Abd al-Muttalib was marked with an ostrich feather. A man from the idolaters said: "Who is that man marked with an ostrich feather?" He was told: "Hamzah bin Abd al-Muttalib." He said: "That is the one who did to us what was done."
