Muwatta Imam Malik Book of Blood-Money, Hadith 8

Yahya related to me from Malik from Da'ud ibn al-Husayn that Abu Ghatafan ibn Tarif al-Murri informed him that Marwan ibn al-Hakam sent him to Abdullah ibn Abbas to ask him what there was for the molar. Abdullah ibn Abbas said, "There are five camels for it." He said, "Marwan sent me back again to Abdullah ibn Abbas.'' He said, "Do you make front teeth like molars?" Abdullah ibn Abbas said, "It is enough that you take the fingers as the example for that, their blood-moneys being all the same."

وَحَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ دَاوُدَ بْنِ الْحُصَيْنِ، عَنْ أَبِي غَطَفَانَ بْنِ طَرِيفٍ الْمُرِّيِّ، أَنَّهُ أَخْبَرَهُ أَنَّ مَرْوَانَ بْنَ الْحَكَمِ بَعَثَهُ إِلَى عَبْدِ اللَّهِ بْنِ عَبَّاسٍ يَسْأَلُهُ مَاذَا فِي الضِّرْسِ فَقَالَ عَبْدُ اللَّهِ بْنُ عَبَّاسٍ فِيهِ خَمْسٌ مِنَ الإِبِلِ . قَالَ فَرَدَّنِي مَرْوَانُ إِلَى عَبْدِ اللَّهِ بْنِ عَبَّاسٍ فَقَالَ أَتَجْعَلُ مُقَدَّمَ الْفَمِ مِثْلَ الأَضْرَاسِ . فَقَالَ عَبْدُ اللَّهِ بْنُ عَبَّاسٍ لَوْ لَمْ تَعْتَبِرْ ذَلِكَ إِلاَّ بِالأَصَابِعِ عَقْلُهَا سَوَاءٌ .
