Merit of Sharing Food
وَعَنْ جَابِرٍ رضى اللَّه عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: طَعَامُ الْوَاحِدِ يكفى الِاثْنَيْنِ، وَطَعَامُ الِاثْنَيْنِ يكفى الْأَرْبَعَةَ، وَطَعَامُ الْأَرْبَعَةِ يكفى الثمانيَة .((رَوَاهُ مُسلم))
Jabir bin 'Abdullah (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "The food of one person suffices for two, the food of two persons suffices for four persons, and the food of four persons suffices for eight persons." [Muslim].
