Is it permissible to lie to the husband to convince him to replace the Christian maid who wears makeup, does not observe Islamic dress, and behaves inappropriately with the husband, given that the husband refuses to replace her unless a fault or condemnation is proven against her?

The husband must be alerted to theous situation of the maid and her display of adornment (tabarruj), and he should be admonished about the necessity of replacing her with a chaste Muslim woman. At the same time, the maid must be advised to adhere to the Islamic etiquette of dress and invited to Islam with wisdom and good counsel. It is forbidden to lie to her or accuse her of something she did not do.
