Musannaf Ibn Abi Shaybah 9107 — A woman whose menstruation lasts

He (Sulayman) said: I asked Qatadah about this and said: If a woman's menstruation lasts a fixed number of days and then exceeds that by five days, what should she do? He said: She should pray. I said: And if it exceeds by four days? He said: She should pray. I said: And if it exceeds by three days? He said: She should pray. I said: And if it exceeds by two days? He said: Those are days of her menstruation. I think he said this from his own opinion.
