عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ أَبِي الْحَسَنِ الرِّضَا ( عليه السلام ) قَالَ الْخُبْزُ الْيَابِسُ يَهْضِمُ الْأُتْرُجَّ .
4. A number of our people have narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad from ibn abu Nasr who has said the following: “Abu al-Hassan, al-Rida’ عليه السلام, has said, ‘Dry bread helps one to digests citron.’”
