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 ‏"‏ ‏.‏
Translation
Jabir b. 'Abdullah reported

I heard Allah'. s Messenger (ﷺ) as saying: Food for one person suffices two persons and food for two persons suffices four persons, and food for four persons suffices eight persons; and in the tradition transmitted on the authority of Ishaq there is no mention of the fact that he heard it directly (from the Holy Prophet).
