What is the ruling on designing advertisements for restaurants that serve alcohol, or for beauty salons and hairdressers that may engage in eyebrow plucking (namṣ), tattooing (washm), and beautifying prostitutes, knowing that the work of bridal beauticians is limited to preparing the bride for her wedding night?

The ruling on advertising restaurants and shops that engage in forbidden activities is based on the nature of the advertisement. If the advertisement is for promoting something forbidden, then it is not permissible. However, if it is solely for promoting something permissible, then there is no objection to it. Nevertheless, it is preferable to boycott such places and refuse to advertise for them absolutely, even for permissible things, as a form of denunciation. As for bridal makeup salons, the adornment they provide is permissible for wives for their husbands, so there is no harm in cooperating with them or advertising for them.
