12-53 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Muhammad ibn Yahya al-Attar quoted on the authority of Muhammad ibn Ahmad ibn Yahya ibn Imran al-Ash’ari, on the authority of Al-Hassan ibn al-Hussein al-Lu’lu’ee, on the authority of Al-Hassan ibn Ali ibn Yusuf; on the authority of Mu’az ibn al-Juwhary, on the authority of Amr ibn Jami’a who linked it up through a chain of narrators to God’s Prophet (MGB),

“There are twelve attributes in brushing the teeth with a toothbrush that is a recommendable practice. It cleans the mouth; pleases the Lord; whitens the teeth; removes the mouth’s bad smell; alleviates the phlegm; stimulates the appetite; increases the good deeds; the angels will testify to it; it strengthens the gums; and it cleans what you recite the Quran with. Also two units of prayers said before which one has brushed his teeth are loved more by the Honorable the Exalted God than seventy units of prayers said without having brushed one’s teeth.”
