Muwatta Malik

Yahya related to me from Malik from Yahya ibn Said that Umar ibn al-Khattab was eating bread with ghee. He summoned one of the desert people and he began to eat and follow the grease in the dish with a morsel of bread. Umar said, ""It is as if you were poor."" He said, ""By Allah. I have not eaten ghee nor have I seen food with it since such- and-such a time."" Umar declared, ""I shall not eat clarified butter until people are given life again like they were first given life,"" (i.e. on the Day of Rising)
