Sahih Bukhari Volume 001, Book 006, Hadith Number 325.
Narated By '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.
