Sahih Bukhari Volume 002, Book 026, Hadith Number 789.
Narated By 'Aisha : We performed Hajj with the Prophet and performed Tawaf-al-ifada on the Day of Nahr (slaughtering). Safiya got her menses and the Prophets desired from her what a husband desires from his wife. I said to him, "O Allah's Apostle! She is having her menses." He said, "Is she going to detain us?" We informed him that she had performed Tawaf-al-Ifada on the Day of Nahr. He said, "(Then you can) depart."
