Does applying kohl to the eye invalidate the state of ihram during Umrah or Hajj?

Using kohl during ihram does not invalidate it. If the kohl contains perfume, its use is forbidden except in cases of necessity, and a fidyah (expiatory offering) is obligatory according to the Malikis, Shafi'is, and Hanbalis. As for the Hanafis, a sadaqah (charity) is due if the perfume was added to the kohl once or twice, and a fidyah is due if it exceeds that.

If the kohl does not contain perfume, it is disliked according to the Hanbalis and Shafi'is if it has a beautifying effect, such as ithmid, and there is no fidyah for it. However, if it does not have a beautifying effect, it is permissible without dislike. The Hanafis do not consider a fidyah due for it. The Malikis consider a fidyah due if its use is for non-necessity, and no fidyah if it is for medicinal purposes.
