Narrated Abu Ubaid: I attended the Eid (prayer) along with Umar. He offered prayer before the sermon. He then said: The Messenger of Allah صلی اللہ علیہ وسلم prohibited fasting on these two days. As regards Id al-Adha, you eat the meat of your sacrificial animals. As for Eid al-Fitr, you break (i. e. end) your fast.

Narrated Abu Saeed Al Khudri: The Messenger of Allah صلی اللہ علیہ وسلم forbade fasting on two days, al-Fitr (breaking the fast of Ramadan) and al-Adha (the day of sacrifice), and wearing a tight single garment the raising of which discloses private parts, and sitting with one's legs drawn up and wrapped in one's garment, and forbade praying at two hours, after the Fajr prayer and after the Asr prayer.
