What is the religious ruling regarding a mother and sister wearing transparent and short clothes in front of their adult sons, and their praising the beauty of some foreign women in front of the married son, and the husband's violent behavior towards his wife when she advised him to forbid them from doing so?

A woman is not permitted to wear transparent or tight clothing that describes her body in front of her mahrams. Describing a woman's beauty to a man is impermissible if it is detailed. The wife was correct in forbidding this objectionable act (munkar), and such prohibition should be done with gentleness and leniency. The husband hitting his wife, insulting her, and describing her as insane is an objectionable act (munkar) that contradicts good marital relations. His claim that what occurred is not a serious objectionable act is false, and he must repent.
