It is narrated from Sayyiduna Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Use a toothpick (between your teeth), for it brings cleanliness, and cleanliness calls to faith, and faith will be with its possessor in Paradise."
No one narrated this hadith from Mughirah (may Allah have mercy on him) except Sharik (may Allah have mercy on him), and no one from Sharik (may Allah have mercy on him) except Ibrahim bin Hayyan (may Allah have mercy on him), while al-Nadr bin Hisham (may Allah have mercy on him) is alone in narrating it.
