Musannaf Ibn Abi Shaybah

Hazrat Ibn Jurayj states that Abdul Aziz bin Umar informed me that the commanders of Ajnad and the people of opinion reached a consensus for Umar bin Abdul Aziz that if a nail is pulled and then becomes damaged, falls off, or turns black, then one-tenth of the compensation for a finger, that is, ten dinars, will be the penalty for it.
