Think carefully before making decisions or taking any action in life; Avoid foolishness; Avoid divorcing your spouse while they are on their period .

This hadith discusses the issue of divorce during menstruation. Ibn 'Umar was asked about a man who divorced his wife while she was menstruating, and he said that 'Abdullah bin 'Umar had done the same thing. He then went to the Prophet and asked him about it, and the Prophet told him to take her back then wait for the right time. Ibn 'Umar then said that this divorce did not count as valid, implying that it should be avoided in general. This hadith teaches us that divorce during menstruation is invalid, so it should be avoided if possible. It also teaches us to think carefully before making decisions or taking any action in life, as foolishness can lead to regretful consequences later on.
