Yusuf bin Mas'ud bin al-Hakam narrates from his grandmother (may Allah be pleased with her) that she saw, while she was at Mina in the time of the Messenger of Allah (peace and blessings be upon him), a rider calling out: "O people! These are days of eating and drinking, days of women and of play, and of the remembrance of Allah." She says: I said: "Who is this?" They said: "Ali bin Abi Talib (may Allah be pleased with him)."
