أَبِی ره قَالَ حَدَّثَنَا أَحْمَدُ بْنُ إِدْرِیسَ قَالَ حَدَّثَنِی مُحَمَّدُ بْنُ أَحْمَدَ قَالَ حَدَّثَنِی إِبْرَاهِیمُ بْنُ إِسْحَاقَ عَنْ مُحَمَّدِ بْنِ عِیسَی عَنْ عُبَیْدِ اللَّهِ الدِّهْقَانِ عَنْ دُرُسْتَ بْنِ مَنْصُورٍ عَنْ عَبْدِ اللَّهِ بْنِ سِنَانٍ عَنْ أَبِی عَبْدِ اللَّهِ ع قَالَ: فِی السِّوَاکِ اثْنَتَا عَشْرَهَ خَصْلَهً هُوَ مِنَ السُّنَّهِ وَ مَطْهَرَهٌ لِلْفَمِ وَ مَجْلَاهٌ لِلْبَصَرِ وَ یُرْضِی الرَّحْمَنَ وَ یُبَیِّضُ الْأَسْنَانَ وَ یَذْهَبُ بِالْحَفْرِ وَ یَشُدُّ اللِّثَهَ وَ یُشَهِّی الطَّعَامَ وَ یَذْهَبُ بِالْبَلْغَمِ وَ یَزِیدُ فِی الْحِفْظِ وَ یُضَاعِفُ الْحَسَنَاتِ وَ تَفْرَحُ بِهِ الْمَلَائِکَهُ.
