What is the ruling regarding a wife who seeks help from those who engage in what displeases Allah to separate her husband from his second wife, conceals her husband’s gifts, disturbs her husband and his second wife at night with false claims, and refuses to swear on the Qur'an when confronted?

It is the right of the husband upon his wife that she obey him, strive for his comfort, and avoid harming him, for his right is great.

The wife mentioned must fear Allah and acknowledge her husband's right, for her disobedience to him and neglect of his rights are causes for entering Hellfire.

A wife's resorting to sorcerers to prevent her husband from his second wife is a repulsive and heinous act, due to the polytheism and corruption it entails. She must repent, seek forgiveness, and immediately cease these actions that incur Allah's wrath.

The husband must forbid his wife from these actions, for he is responsible for her. He should follow the guidance of Allah Almighty in rectifying her, as He said: "But those [wives] from whom you fear defiance - [first] advise them; then if they persist, forsake them in bed; and [finally], strike them."
