It was narrated that 'Aishah said: "I never saw any woman who made food like Safiyyah. She sent a dish to the Prophet (ﷺ) in which was some food, and I could not keep myself from breaking it. I asked the Prophet (ﷺ) what the expiation was for that, and he said: 'A dish like that dish, and food like that food.'"
