The Prophet ﷺ said: The fingers are equal and the teeth are equal. The front tooth and the molar tooth are equal, this and that are equal. Abu Dawud said: Nadr b. Shumail transmitted it from Shu'bah to the same effect as mentioned by 'Abd al-Samad. Abu Dawud said: al-Darimi narrated it to me from al-Nadr.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ الأَصَابِعُ سَوَاءٌ وَالأَسْنَانُ سَوَاءٌ الثَّنِيَّةُ وَالضِّرْسُ سَوَاءٌ هَذِهِ وَهَذِهِ سَوَاءٌ  

Yahya related to me from Malik that he had heard that the Messenger of Allah ﷺ said, "I forget or I am made to forget so that I may establish the sunna."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنِّي لأَنْسَى أَوْ أُنَسَّى لأَسُنَّ  

الأسنان سواء الثنية والضرس سواء".
