Hazrat Hamnah bint Jahsh says that she suffered from excessive istihada (non-menstrual bleeding) during the time of the Messenger of Allah, peace and blessings be upon him. She presented herself before the Messenger of Allah, peace and blessings be upon him, and said, "I am afflicted with extremely severe istihada." The Prophet, peace and blessings be upon him, said, "Tie a piece of cotton firmly with cloth." She said, "It is much more than that and keeps flowing." The Prophet, peace and blessings be upon him, said, "Put on a cloth belt and, according to Allah’s knowledge, spend six or seven days each month as menstruation, then perform ghusl (ritual bath), and for twenty-three or twenty-four days, offer prayers and keep fasts. Delay the Zuhr prayer and offer Asr early, and perform one ghusl for both. Then delay Maghrib and offer Isha early, and perform one ghusl for both. Of these two options, this is more preferable to me."

The Noble Prophet, peace and blessings be upon him, said: A woman experiencing istihada (non-menstrual bleeding) should refrain from prayer during the days of her menstruation, then perform ghusl, make ablution for every prayer, fast, and perform the prayers.

It is also narrated in the same way through the chain of Hazrat Ali (may Allah be pleased with him).

Hazrat Abu Ja'far says regarding the woman with istihada that this is a trick of Satan. When the blood becomes excessive, she should place a cloth and after the menstruation, perform ghusl and do wudu.

Hazrat Anas bin Sirin says that a woman from the family of Anas had istihada (non-menstrual bleeding). People instructed me to investigate her case. I asked Ibn Abbas (may Allah be pleased with them) and he said: If she sees continuous blood, she should not pray, and if she sees purity even for a part of the day, she should perform ghusl and pray.

Hazrat Zainab bint Umm Salamah narrates that I saw bint Jahsh. She was suffering from istihada (non-menstrual bleeding), and the bleeding was excessive, yet she used to perform prayers.

Hasan says that a woman experiencing istihada will perform ghusl from the Zuhr prayer of one day until the Zuhr prayer of the next day.
