Musnad Abu Ya'la al-Mawsili 6:107

Abu Khaythama narrated to us, Ja'far bin 'Awn narrated to us, Yahya bin Sa'id informed us, he said: I heard Sa'id bin al-Musayyib saying: I heard Sa'd saying: "The Messenger of Allah (may Allah bless him and grant him peace) gathered his parents for me on the day of Uhud." Yahya said: I think he said: "May my father and mother be sacrificed for you." And Sa'd was an excellent archer.
