Is it permissible for a man to dye his hands and feet with henna (a plant that produces a reddish-orange dye)?
It is permissible for a man to do so for the purpose of healing. However, if he does that for the purpose of adorning himself and imitating women, this is not permissible according to the following Hadith:
The Messenger of Allah (peace be upon him) has cursed the men who imitate women and the women who imitate men.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
