What is the ruling on selling condoms, alcoholic medicines, sexual enhancers, and breast enlargers, and what is the ruling on looking at unveiled women during a sale?

Selling should be restricted to permissible (halal (definition)) items. Therefore, it is not advisable to sell condoms to those who use them for illicit sexual relations (zina). As for alcoholic medicines, it is permissible to sell them if the alcohol is essential and its proportion is small. It is permissible to sell medications that increase sexual desire to married couples. It is not permissible to sell substances that alter breast size because they constitute a change to Allah's creation. However, there is no harm in selling substances that make them firm without changing their size. We advise lowering the gaze to avoid falling into illicit sexual relations (zina).
