[Machine] I asked the Messenger of Allah ﷺ about Al-Mustahadah (a woman with irregular bleeding outside her menstrual period). He said, "She should sit (i.e., refrain from prayer) during the days of her menstruation, then perform ablution at each time of purity, then wear a sanitary pad, and then pray. And so on."
سَأَلْتُ رَسُولَ اللهِ ﷺ عَنِ الْمُسْتَحَاضَةِ فَقَالَ تَقْعُدُ أَيَّامَ أَقْرَائِهَا ثُمَّ تَغْتَسِلُ عِنْدَ كُلِّ طُهْرٍ ثُمَّ تَحْتَشِي ثُمَّ تُصَلِّي وَهَكَذَا
