Messenger of Allah (peace and blessings of Allah be upon him) said: "This and this are the same," meaning the thumb and the little finger. It was reported by al-Bukhari and Abu Dawud (11). In the document of the Prophet (peace and blessings of Allah be upon him) to ‘Amr ibn Hazm: "And for every finger from the [hand and foot] (12) is ten camels" (13). This is because it is a category possessing a number in which the blood money is obligatory, so they are equal in (14) blood money, like the teeth, the eyelids, and the rest of the limbs. The blood money for each finger is divided across its phalanges; every finger has three phalanges except the thumb, for it has two phalanges. Thus, for every phalanx other than the thumb is one-third of the blood money of the thumb, which is three and one-third camels, and for every phalanx of the thumb is five camels, half of its blood money. It has been narrated from Malik that he said: "The thumb also has three phalanges, one of which is internal." This is not correct, for the consideration is with what is apparent. His statement (peace and blessings of Allah be upon him), "For every finger is ten camels," necessitates the obligation of the ten for what is apparent, because it is the finger to which the name applies, not what is internal of it, just as the tooth for which the blood money obligation is attached is the one apparent from the [flesh of the gum] (15), not its root. The ruling regarding the fingers of the hands and the feet is the same due to the generality of the report regarding both, and the agreement reached upon them.

Section: For a supernumerary (extra) finger, there is a compensatory assessment (hukuma). This is also the opinion of al-Thawri, al-Shafi‘i, and the People of Opinion. It is reported from Zayd ibn Thabit that for it is one-third of the blood money of a finger (16). The Qadi mentioned that this is the analogy (qiyas) of the school, based on the report of the obligation of one-third for a paralyzed hand. The former is more correct because one does not resort to a specific estimation (taqdir) except by a text (tawqif) or by analogy (17) to that which has a text, and that is not the case here, because the paralyzed hand
