Narrated Abu Ubaid: I attended the Eid (prayer) along with Umar. He offered prayer before the sermon. He then said: The Messenger of Allah ﷺ 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.
