It is narrated from Hazrat Mutalib that he invited a Bedouin to eat after the day of Eid al-Adha. The Bedouin said, "I am fasting." So Hazrat Mutalib said, "Indeed, I heard Sayyiduna Abdullah bin Umar (may Allah be pleased with them) saying that I heard the Messenger of Allah (peace and blessings be upon him) forbidding fasting on these days."
