“The food of one person is sufficient for two, the food of two is sufficient for four, and the food for four is sufficient for eight.” (Using translation from Ibn Mājah 3254)
قَالَ رَسُولُ اللهِ ﷺ طَعَامُ الْوَاحِدِ يَكْفِي الِاثْنَيْنِ وَطَعَامُ الِاثْنَيْنِ يَكْفِي الْأَرْبَعَةَ وَطَعَامُ الْأَرْبَعَةِ يَكْفِي الثَّمَانِيَةَ
