What is the ruling on a husband falsely accusing his wife of adultery to seize her entitlements, and what should the wife do when her daughter has been taken from her?

If the husband slanders his wife and accuses her of something she is innocent of, and seizes her rights and those of her daughter, he has committed grave sins that necessitate repentance. This repentance involves him disclaiming his own accusations, restoring her rights to her, and returning her daughter to her. The wife has the right to take her case to court to demand her rights, including the implementation of the Hadd punishment for slander against the husband, unless he performs li'an.
