Narrated Abu Bakr ibn Abi Shaybah: Abu Usamah narrated to us, from Hisham, from his father, from Aisha, who said: Abu Bakr entered upon me while I had two young girls from the girls of the Ansar with me, singing the verses that the Ansar had exchanged with one another on the Day of Bu'ath. She said: And they were not singers. Abu Bakr said: "A flute of Satan in the house of the Messenger of Allah, peace and blessings be upon him?" And that was on the day of Eid. So the Messenger of Allah, peace and blessings be upon him, said: "O Abu Bakr, indeed every people has a festival, and this is our festival."
