Istihadha is a special situation that some Muslim women may experience. It's when a woman needs to take a break from having periods. This can happen if a woman gets hurt, or is feeling very ill or weak, or if she is pregnant or breastfeeding. During this time, she won't be expected to do any prayers or fasts. Instead, she'll be able to rest and take care of herself. After the Istihadha period is over, the woman can start doing her prayers and fasts again.
