Sayyiduna Umar (may Allah be pleased with him) said: "These are two days whose fasting the Messenger of Allah (peace and blessings of Allah be upon him) forbade: the day of breaking the fast after (the fasts of) Ramadan (i.e., Eid al-Fitr), and the other day on which you eat the meat of your sacrifice (i.e., the day of Eid al-Adha)."
