وَ بِهَذَا الْإِسْنَادِ قَالَ قَالَ أَمِيرُ الْمُؤْمِنِينَ ( عليه السلام ) السِّوَاكُ مَطْهَرَةٌ لِلْفَمِ وَ مَرْضَاةٌ لِلرَّبِّ .
4. Through the same chain of narrators as that of the previous Hadith the following is narrated: “He (the Imam) said that ’Amir al-Mu’minin has said, ‘Brushing one’s teeth cleanses the mouth and earns Allah’s pleasure.’”
