#287 Muhammad bin Yusuf informed us, Sufyan narrated to us, from Yunus bin Ubayd, from al-Hasan, from Uthman bin Abi al-As, that he would not approach a woman in postpartum bleeding for forty days. And al-Hasan said: "Postpartum bleeding is forty-five to fifty days; whatever exceeds that, then she is considered a mustahadah (one experiencing chronic non-menstrual bleeding)."
