Is using ithmid kohl disliked for a Muhrim?
Chapter on What the Muhrim Must Avoid and What is Permissible for Him
Al-Mughni
Book of Hajj
Primary text
If it is established that applying kohl generally implies adornment, then the use of ithmid kohl is disliked, but it does not necessitate a penalty (fidya). There is no known dispute regarding the non-necessity of fidya. Aisha stated that a woman experiencing eye trouble while in Ihram should use any kohl except ithmid, noting it is not forbidden but is adornment, which they dislike. Al-Shafi'i stated that if a Muhrim does it, there is no fidya known upon them.
