Al-Kāfi|Volume 6|Book 7|Chapter 31
ابْنُ مَحْبُوبٍ عَنِ الْعَلَاءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ رَأَيْتُ أَبَا جَعْفَرٍ ( عليه السلام ) يَمْضَغُ عِلْكاً فَقَالَ يَا مُحَمَّدُ نَقَضَتِ الْوَسِمَةُ أَضْرَاسِي فَمَضَغْتُ هَذَا الْعِلْكَ لِأَشُدَّهَا قَالَ وَ كَانَتِ اسْتَرْخَتْ فَشَدَّهَا بِالذَّهَبِ .
3. Ibn Mahbub has narrated from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “I once saw abu Ja‘far عليه السلام, chewing gums and he (the Imam) said, ‘O Muhammad, woad has loosened my molar teeth so I chew gums to strengthen them . 5 His teeth had become loose so he tied them with gold.”
