Abu Ghatafan bin Tarif al-Murri said: Marwan bin al-Hakam sent me to Ibn Abbas (may Allah be pleased with him) to ask about the diyah for a molar, and he replied that there are five camels for it. He sent me again to ask: Do you consider a front tooth and a molar to be equal? Ibn Abbas (may Allah be pleased with him) replied: Not only these; the fingers too are all equal. Imam al-Shafi'i (may Allah have mercy on him) said: What Ibn Abbas (may Allah be pleased with him) said is correct, if Allah wills. The diyah is fixed according to number, not according to usefulness.
