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 عليه السلام. He (the Imam) said, ‘It kills dawab (the insects) in the belly and strengthens the mouth (the teeth).’”
