عَلِيٌّ عَنْ أَبِيهِ عَنْ حَنَانٍ عَنْ أَبِيهِ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ ذُكِرَ عِنْدَهُ خَلُّ الْخَمْرِ فَقَالَ ( عليه السلام ) إِنَّهُ لَيَقْتُلُ دَوَابَّ الْبَطْنِ وَ يَشُدُّ الْفَمَ .
8. Ali has narrated from his father from Hanan ibn Sadir from his father who has said the following: “Once, vinegar of wine (clean grape juice with vinegar in it placed in the sun to turn the whole thing into vinegar) was mentioned before abu ‘Abd Allah . He (the Imam) said, ‘It kills dawab (the insects) in the belly and strengthens the mouth (the teeth).’”
