Muwatta Malik Hadith 435

Yahya related to me from Malik from Ibn Shihab that Abu Ubayd, the mawla of Ibn Azhar said, "I was present at an id with Umar ibn al- Khattab. He prayed, and then after he had prayed he gave a khutba to the people and said, 'The Messenger of Allah, (ﷺ), forbade fasting on these two days - the day you break your fast (after Ramadan), and the day you eat from your sacrifice (after Hajj) .' " Abu Ubaydcontinued,"Then I was present at an id with Uthman ibn Affan. He came and prayed, and when he had finished he gave a khutba and said, 'Two ids have been joined together for you on this day of yours. If any of the people of al-Aliyya (the hills outlying Madina) want to wait for the jumua they can do so, and if any of them want to return, I have given them permission.' Abu Ubayd continued, "Then I was present at an id with AIi ibn Abi Talib (at the time when Uthman was being detained). He came and prayed, and then after he had prayed he gave a khutba."
