Any blood that falls on the clothes you will be wearing in Salah or your prayer mat must be washed off. If
you are suffering from Istihadah, you should perform Wudu', protect yourself against leakage by wearing a pad or the like, and offer the obligatory Salah. It is permissible for you to offer any supererogatory Salahs until the prescribed time of the next obligatory Salah comes, for which you should offer new Wudu', as you did for the previous obligatory one.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
