Qatadah narrates from Anas (may Allah be pleased with him): The Prophet Muhammad (peace and blessings be upon him) forbade fasting on five days of the year: "The day of Eid al-Fitr, the day of Eid al-Adha, and the three days of Tashreeq." The narrator named Uthman states: We have narrated this same report from Muhammad bin Khalid.
