Hadith.5334 - Abu Abdullah (as) was asked about a man who kicked a woman in her private area, and she claimed that her menstruation had stopped while it was previously regular.
Imam (as) said: "She should be observed for one year. If her menstruation returns, then nothing is required. But if it does not return, the man must pay one-third of her blood money (diyyah) for the damage to her menstruation and the harm caused to her womb."
