Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) said: "The fingers are all equal in diyah, and the teeth are equal too." And in the narration of Abu Qilabah it is likewise: "The ordinary tooth and the molar, and the little finger and the thumb, these too are equal."
