Recreation, amusements, and singing, if they stay within the moral bounds, are permissible on the days of ‘id.
Anas reports: “When the Prophet came to Medinah they had two days of sport and amusement. The Prophet said: “Allah, the Exalted, has exchanged these days for two days better than them: the day of breaking the fast and the day of sacrifice.” This is related by an-Nasa’i and Ibn Hibban with a sahih chain.
‘Aishah says: “The Abyssinians were performing in the mosque on the day of ‘id. I looked over the Prophet’s shoulders and he lowered them a little so I could see them until I was satisfied and left.” This is related by Ahmad, al-Bukhari, and Muslim.
Ahmad, al-Bukhari, and Muslim also record that she said: “Abu Bakr entered upon us on the day of ‘id and there were some slave girls who were recounting [in song the battle of] Bu’ath in which many of the brave of the tribes of Aus and Khazraj were killed. Abu Bakr said: ‘Slaves of Allah, you play the pipes of the Satan!’ He said it three times. The Prophet said to him: ‘O Abu Bakr, every people have a festival and this is our festival.”‘ In al-Bukhari’s version, ‘Aishah said: “The Messenger of Allah, entered the house and I had two girls who were singing about the battle of Bu’ath. The Prophet lied down on the bed and turned his face to the other direction. Abu Bakr entered and spoke harshly to me, ‘Musical instruments of the Satan in the presence of the Messenger of Allah!’ The Messenger of Allah turned his face to him and said: ‘Leave them.’ When Abu Bakr became inattentive I signaled to the girls to leave. It was the day of ‘id and the Africans were performing with their shields and spears. Either I asked him or the Prophet asked if I would like to watch them [I don’t recall now]. I replied in the affirmative. At this the Prophet made me stand behind him and my cheek was against his. He was saying: ‘Carry on, O tribe of Arfadah,’ until I tired. The Prophet asked: ‘Is that enough for you?’ I replied: “yes,” so he said: ‘Leave [then].'”
Ibn Hajar writes in Fath al-Bari, “Ibn as-Siraj related from Abu az-Zinad on the authority of ‘Urwah from ‘Aishah that the Prophet said that day: ‘Let the Jews of Medinah know that our religion is spacious [and has room for relaxation] and I have been sent with an easy and straight forward religion. “‘
Ahmad and Muslim record from Nubaishah that the Prophet sallallahu alehi wasallam said: “The days of tashriq (i.e., the days in which the ‘id is celebrated) are days of eating and drinking [non alcoholic drinks] and of remembering Allah, the Exalted.”
