وَعَنْ جَابِرٍ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «طَعَامُ الْوَاحِدِ يَكْفِي الِاثْنَيْنِ وَطَعَامُ الِاثْنَيْنِ يَكْفِي الْأَرْبَعَةَ وَطَعَامُ الْأَرْبَعَةِ يَكْفِي الثمانيَة» . رَوَاهُ مُسلم

Jabir told of hearing God's messenger say, “One person’s food is enough for two, two persons’ food is enough for four, and four persons' food is enough for eight.” Muslim transmitted it.
