What is the ruling on buying a bracelet for a female relative who does not wear it for good luck, but will wear it in front of non-mahram men while rolling up her sleeve, and what is the ruling on gifting her an accessory that she will wear as described?

A Muslim woman must cover her face and hands, and any jewelry or adornments on them, in front of non-mahram men. It is not permissible to buy adornments or jewelry for a woman who will display them in front of non-mahram men, as this constitutes cooperation in sin, in accordance with the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." Furthermore, wearing an amulet (bracelets like 'al-ḥaẓẓāẓah') is not permissible because it falls under the category of amulets that are forbidden by Islamic law.
