حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الرَّقِّيُّ، حَدَّثَنَا يَحْيَى بْنُ زِيَادٍ الأَسَدِيُّ، أَنْبَأَنَا ابْنُ جُرَيْجٍ، أَنْبَأَنَا أَبُو الزُّبَيْرِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " طَعَامُ الْوَاحِدِ يَكْفِي الاِثْنَيْنِ وَطَعَامُ الاِثْنَيْنِ يَكْفِي الأَرْبَعَةَ وَطَعَامُ الأَرْبَعَةِ يَكْفِي الثَّمَانِيَةَ " .
