The Book of Drinks
The virtue of sharing a small amount of food, and the food of two is sufficient for three, and so on.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّهُ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم طَعَامُ الاِثْنَيْنِ كَافِي الثَّلاَثَةِ وَطَعَامُ الثَّلاَثَةِ كَافِي الأَرْبَعَةِ .
Abu Huraira reported Allah's Messenger (ﷺ) as saying: Food for two persons suffices three persons and food for three persons suffices four persons.
