It is narrated from Hazrat Aisha (may Allah be pleased with her) that once on the day of Eid, Hazrat Abu Bakr Siddiq (may Allah be pleased with him) came to her house, and there were two girls playing the duff and mentioning the Battle of Bu'ath, in which the prominent leaders of Aws and Khazraj were killed. Hazrat Abu Bakr Siddiq (may Allah be pleased with him) scolded them, so the Prophet (peace and blessings be upon him) said to him, "Leave them, for every nation has a festival, and today is our festival."
