It is narrated from Sayyidah Aishah (may Allah be pleased with her) that on the day of Eid two slave girls were singing in her presence while the Messenger of Allah (peace and blessings be upon him) was with her and was not forbidding them. Then Abu Bakr (may Allah be pleased with him) came in and scolded her (Sayyidah Aishah), so the Messenger of Allah (peace and blessings be upon him) said: "Leave her, O Abu Bakr! Every people has an Eid, and this is our Eid."
