(27) CHAPTER. If a woman gets her menses after Tawaf-al-Ifada.
Narrated `Aisha: (the wife of the Prophet) I told Allah's Apostle that Safiya bint Huyai had got her menses. He said, She will probably delay us. Did she perform Tawaf (Al-Ifada) with you? We replied, Yes. On that the Prophet told her to depart.
Narrated Ibn `Abbas: A woman is allowed to leave (go back home) if she gets menses (after Tawaf-Al-Ifada).
Ibn `Umar formerly used to say that she should not leave but later on I heard him saying, She may leave, since Allah's Apostle gave them the permission to leave (after Tawaf-Al-Ifada).
