What is the Sharia ruling on feeling repulsion towards dealing with a woman who plucks her eyebrows (al-mutanammisah), and not eating or drinking from her hand, due to the belief that she is cursed?

Sins that incur a curse do not necessarily mean that the curse will afflict the doer, as they may have good deeds or impediments that avert the effect of their sin. It is not permissible to curse a specific Muslim by name, even if they commit a major sin that warrants a curse. Rather, general texts are used for deterrence. The specific person may have strived and erred, or be ignorant, or possess faith and good deeds that atone for them. Abstaining from buying from or eating food prepared by a woman who plucks her eyebrows (al-mutanammisah) is not obligatory, as it is permissible to deal with disobedient individuals, and it is more appropriate to advise them with wisdom.
