Sulayman bin Yasar (may Allah have mercy on him) narrates from a man of the Ansar (may Allah be pleased with him) that a woman bled continuously. He narrated a hadith with the same meaning as that of al-Layth and said: "When that amount has passed and the time of prayer has come, she should take a ritual bath," and the rest is the same.
