Musannaf Ibn Abi Shaybah

Hazrat Amr bin Shu'aib narrates that the decision made by Hazrat Abu Bakr and Umar regarding a wound was that if, due to the hand, the owner of the hand could neither eat nor tie a lower garment nor perform istinja, then full blood money (diyah) would be due; and if the wound was less than this, then the blood money would be according to the extent of the injury.
