Yahya related to me from Malik from Abu'z-Zinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, "The food of two is enough for three, and the food of three is enough for four."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " طَعَامُ الاِثْنَيْنِ كَافِي الثَّلاَثَةِ وَطَعَامُ الثَّلاَثَةِ كَافِي الأَرْبَعَةِ " .
