´It was narrated from Sa'eed bin al-Musayyab that:` when the letter was found that was with the family of 'Amr bin Hazm, which they said the Messenger of Allah had written to them, they found in it, with regard to fingers, that the Diyahwas ten (Camels) for each.
Hadith Referenceسنن نسائي / كتاب القسامة والقود والديات / 4850
Narrated Abu Musa: The Prophet ﷺ said: The fingers are equal: ten camels for each finger.
Shaykh Umar Farooq Saeedi
Benefits and Issues: Whether the fingers are of the hand or the foot, whether it is the thumb, the little finger, etc., all are equal; for each one, the compensation (diyah) is ten camels.
