Al-Adab Al-Mufrad #1271

Al-Fadil ibn Muslim reported that his father said, "When 'Ali, may Allah be pleased with him, went out through the Bab al-Qasr, he saw some backgammon players. He took them and locked them up from morning to night. Some of them he only locked up for half the day. Those he locked up until night were those who used silver. Those he locked up for half the day were those who played it. He also commanded that they should not be greeted."
