Seek knowledge, seek guidance from knowledgeable people before making decisions regarding personal matters, be just towards women.

This hadith is about the Islamic ruling on divorcing a woman during her menstruation. According to the hadith, Ibn 'Umar divorced his wife while she was in her menstrual cycle. He then went to the Prophet Muhammad for advice and was told that he should take his wife back and wait until she becomes pure before deciding whether or not he wants to divorce her again. This hadith teaches us that it is not permissible in Islam for a man to divorce his wife while she is in her menstrual cycle as it can be considered an act of injustice towards women. It also teaches us that we should seek advice from knowledgeable people before making any decisions regarding our personal matters as they may have more insight into what is best for us.
