I’m from France. I wish to open a perfume store for men and women. Am I responsible for the women who buy the perfumes and apply it outside the house, and do I have to place a public sign that such a thing is not permissible for women to do?

Shaykh Ṣāliḥ ibn Fawzān al-Fawzān:

Not at all. Sell perfume to both men and women. The women are responsible for how they use it. You are not responsible.
