مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ مُحَمَّدِ بْنِ سِنَانٍ قَالَ سَأَلْتُ أَبَا الْحَسَنِ الرِّضَا ( عليه السلام ) عَنِ الْفُقَّاعِ فَقَالَ هُوَ الْخَمْرُ بِعَيْنِهَا .
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad [ibn ‘Isa] from Muhammad ibn Sinan who has said the following: “I once asked abu al-Hassan, al-Rida’ (a.s.), about al-Fuqa’ . He (the Imam) said, ‘It is wine exactly.’”
