What did Prophet Muhammad (peace be upon him) say to Abu Bakr when he expressed his objection to musical instruments in the house of Allah's Apostle?
 Narrated Aisha:                     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."
