1ـ رسولُ اللهِِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ): لَولا أن أشُقَّ على اُمَّتي لأَمَرتُهُم بِالسِّواكِ مَع كُلِّ صلاةٍ.
1– The Prophet (SAWA) said, 'If it were not for the fact that it would inconvenience my community, I would have commanded them to brush their teeth before every prayer.’[al-Kafi, v. 3, p. 22, no. 1]
2ـ رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ) ـ في وصيَّتِهِ لعليٍّ (عَلَيهِ الّسَلامُ) ـ: علَيكَ بالسِّواكِ عِندَ كُلِّ وُضوءٍ.
2– The Prophet (SAWA) said in his advice to Imam Ali (AS), 'You must brush your teeth at every ablution.’[Bihar al-Anwar, v. 77, p. 69, no. 8]
3ـ رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ) ـ أيضا ـ: يا عليُّ ، علَيكَ بالسِّواكِ ، وإن استَطَعتَ أن لا تُقِلَّ مِنهُ فافعَلْ ، فإنَّ كُلَّ صلاةٍ تُصَلِّيها بالسِّواكِ تَفضُلُ على التي تُصَلِّيها بغَيرِ سِواكٍ أربَعينَ يَوماً.
3- The Prophet (SAWA) also said in his advice to Imam Ali (AS), 'O Ali, you must brush your teeth as frequently as possible, for verily a single prayer that you perform after having brushed your teeth is better than forty days worth of prayers performed without doing so.’[Bihar al-Anwar, v. 76, p. 137, no. 48]
4ـ رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ): الوُضوءُ شَطرُ الإيمانِ ، والسِّواكُ شَطرُ الوُضوءِ.
4– The Prophet (SAWA) said, 'Ablution is a main part of faith, and brushing one's teeth is a main part of ablution.’[Kanz al-`Ummal, no. 26200]
5ـ رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ): طَيِّبُوا أفواهَكُم بِالسِّواكِ؛ فإنّها طُرُقُ القُرآنِ .
5– The Prophet (SAWA) said, 'Freshen your mouths by brushing, for verily they are the means to the Qur'an.’[Kanz al-`Ummal, 2753]
6ـ رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ): مازالَ جَبرئيلُ يُوصِيني بالسِّواكِ حتّى ظَنَنتُ أ نّهُ سَيَجعَلُهُ فَريضَةً .
6– The Prophet (SAWA) said, 'Gabriel continuously advises me about brushing teeth, that I really thought he would lay it down as an obligation.’[Bihar al-Anwar, v. 76, p. 126, no. 2]
7ـ الإمامُ الصّادقُ (عَلَيهِ الّسَلامُ) ـ لَمّا سُئلَ: أتَرى هذا الخَلقَ كُلَّهُ مِنَ الناسِ ؟ ـ: فقالَ: ألْقِ مِنهُمُ التارِكَ للسِّواكِ .
7– Imam al-Sadiq (AS) was once asked, 'Do you consider all of these people as being real human beings [true to their nature]?' to which he replied, 'Exclude from them the one who does not brush his teeth, …'[Bihar al-Anwar, p. 128, no. 11].
This is part of a longer tradition where the Imam cites several other categories of people whom he excludes from the banner of humanity for their various faults, in accordance with the verse of the Qur'an (25:44): "Do you suppose that most of them listen or apply reason? They are just like cattle; rather they are further astray from the way.”
