Menstrual Periods

Bukhari :: Book 1 :: Volume 6 :: Hadith 326

Narrated Ibn 'Abbas:

A woman is al lowed to leave (go back home) if she gets menses (after Tawaf-AlIfada). 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-AlIfada."
