عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ عَنْ أَبِي الْحَسَنِ الرِّضَا ( عليه السلام ) قَالَ لَا تَقْطَعُوا الْخُبْزَ بِالسِّكِّينِ وَ لَكِنِ اكْسِرُوهُ بِالْيَدِ وَ خَالِفُوا الْعَجَمَ .
14. Afi ibn Ibrahim has narrated from Muhammad ibn ’Isa from Yunus who has said the following: “Abu al-Hassan, al-Rida’ , has said, ‘Do not cut bread with knife, instead break it with the hands and do the opposite of al-Ajam (non- Arabs).”’
