Volume 2, Book 15, Number 70:
Allah's Apostle (p.b.u.h) came to my house while two girls were singing beside me the songs of Buath (a story about the war between the two tribes of the Ansar, the Khazraj and the Aus, before Islam). The Prophet (p.b.u.h) lay down and turned his face to the other side. Then Abu Bakr came and spoke to me harshly saying, "Musical instruments of Satan near the Prophet (p.b.u.h) ?" Allah's Apostle (p.b.u.h) turned his face towards him and said, "Leave them." When Abu Bakr became inattentive, I signalled to those girls to go out and they left. It was the day of 'Id, and the Black people were playing with shields and spears; so either I requested the Prophet (p.b.u.h) or he asked me whether I would like to see the display. I replied in the affirmative. Then the Prophet (p.b.u.h) made me stand behind him and my cheek was touching his cheek and he was saying, "Carry on! O Bani Arfida," till I got tired. The Prophet (p.b.u.h) asked me, "Are you satisfied (Is that sufficient for you)?" I replied in the affirmative and he told me to leave.
Abu Bakr came to my house while two small Ansari girls were singing beside me the stories of the Ansar concerning the Day of Buath. And they were not singers. Abu Bakr said protestingly, "Musical instruments of Satan in the house of Allah's Apostle !" It happened on the 'Id day and Allah's Apostle said, "O Abu Bakr! There is an 'Id for every nation and this is our 'Id."
Narrated 'Urwa on the authority of 'Aisha:
On the days of Mina, (11th, 12th, and 13th of Dhul-Hijjah) Abu Bakr came to her while two young girls were beating the tambourine and the Prophet was lying covered with his clothes. Abu Bakr scolded them and the Prophet uncovered his face and said to Abu Bakr, "Leave them, for these days are the days of 'Id and the days of Mina." 'Aisha further said, "Once the Prophet was screening me and I was watching the display of black slaves in the Mosque and ('Umar) scolded them. The Prophet said, 'Leave them. O Bani Arfida! (carry on), you are safe (protected)'."
