The freed slave of Aqil bin Abi Talib (may Allah be pleased with him) narrates: Abdullah bin Amr (may Allah be pleased with them both) and I went to Amr bin al-As (may Allah be pleased with him); this was on the first or second day after Eid al-Adha. Amr (may Allah be pleased with him) placed food before him, and Abdullah (may Allah be pleased with them both) said: I am fasting. So Amr (may Allah be pleased with him) said to him: "Break your fast; these are among the days on which the Messenger of Allah (peace and blessings be upon him) used to order us to break the fast and forbid us from fasting." Then Abdullah (may Allah be pleased with them both) broke his fast and ate, and we ate with him.
