Answered by our Shaykh, the ‘Allaamah, the Sincere Adviser, Abu ‘Abdirrahman Yahya bin ‘Ali Al-Hajoori – may Allaah preserve him –
What’s the ruling of using kohl for men?
The kohl which contains Ithmid (antimony) for men is a good affair, it improves the vision. As for it being without Ithmid whereby it doesn’t contain any benefit for men then it’s from the particularities of women; so that’s avoided as to not resemble them.
Translated by Abu ‘Abdirrahman ‘Abdullaah bin Ahmed Ash-Shingaani
