Muwatta Malik · Hadith 1574
وَحَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّهُ كَانَ يَقُولُ إِذَا أُصِيبَتِ السِّنُّ فَاسْوَدَّتْ فَفِيهَا عَقْلُهَا تَامًّا فَإِنْ طُرِحَتْ بَعْدَ أَنْ تَسْوَدَّ فَفِيهَا عَقْلُهَا أَيْضًا تَامًّا .
Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyab used to say,' 'When a tooth is struck and becomes black, there is complete blood- money for it. If it falls out after it becomes black, there is also the complete blood-money for it
