Who bears the penalty (Fidya) if a Muhrim shaves the head of another Muhrim without his permission (i.e., under compulsion or while asleep)?
Chapter on Ransom (Fidyah) and Penalty for Hunting
Al-Mughni
Book of Hajj
Primary text
If the shaver acts under compulsion (Mukrah) or while the person whose head is shaved is asleep, there is no Fidya incumbent upon the person whose head was shaved. This view is held by Ishaq, Abu Thawr, Ibn al-Qasim (the companion of Malik), and Ibn al-Mundhir.

Abu Hanifa holds that the Fidya is incumbent upon the one whose head was shaved. A narration from Al-Shafi'i supports both opinions mentioned above (the main ruling and the ruling of Abu Hanifa).
