فَحُكْمُهُ حُكْمُ الرُّعَافِ: لَا يَمْنَعُ الصَّلَاةَ، وَلَا الصَّوْمَ، وَلَا الْوَطْءَ.
Meaning: Its ruling is like nosebleeding: it does not prohibit prayer, fasting or marital intimacy.
The comparison to nosebleeding indicates that it may affect wudu and cleanliness but does not carry the prohibitions of hayd. Continuous bleeding brings the special rules for an excused person.
