Musannaf Ibn Abi Shaybah

Hazrat Khalid bin Arara narrates that a man asked Hazrat Ali (may Allah be pleased with him): "If a woman fears wrongdoing or neglect from her husband, what should she do?" He replied: "This refers to a woman whose husband is troubled by her bad character, poverty, and inappropriate behavior, and he wishes to leave her, but the wife is not willing to separate from him. If the woman gives up some amount from her dower for him, it is permissible for the man, and if the woman relinquishes her right, there is no harm in that either."
