I heard the Messenger of Allah ﷺ say, "Food enough for one suffices two, food enough for two suffices four, and food enough for four suffices eight."
سمعت رسول الله ﷺ يقول: طعام الواحد يكفي الاثنين، وطعام الاثنين يكفي الأربعة، وطعام الأربعة يكفي الثمانية.
Muslim narrated it in the Book of Drinks (2059:179) via the route of Rawh, who said, Ibn Jurayj narrated to us, Abu Zubayr informed me that he heard Jabir bin Abdullah, and he mentioned it. He also narrated it (181) via the route of Abu Sufyan, from Jabir, in a similar manner.
