Musannaf Ibn Abi Shaybah 28645 — The lips: what is due for them?

Mujahid said: For the two lips there are fifty camels each. The lower lip of a man or a woman is given preference through the aggravated form of blood money (diyah) (mughallazah), but it is not given preference by an increase in number. The aggravation for the lower lip is in the ages of the camels.
