Yahya related to me from Malik from Da'ud ibn al-Husayn that AbuGhatafan ibn Tarif al-Murri informed him that Marwan ibn al-Hakam senthim 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 youmake front teeth like molars?" Abdullah ibn Abbas said, "It is enoughthat you take the fingers as the example for that, their blood-moneysbeing all the same."
