Is it permissible for a wife to dance for her husband to the beats of songs whose lyrics have been removed to make them permissible, especially since her husband does not find her dancing to Islamic hymns beautiful?

There is no harm in a wife dancing for her husband to the tunes of songs free from obscenity and musical instruments. However, this is not obligatory for her, and she is not considered negligent in her husband's rights if she does not do so.
