Sahih Muslim Book 7, Hadith Number 3061.

Chapter : It is obligatory to perform farewell circumambulation, while a menstruating woman i., exempted from it.

This Hadith is narrated (from ‘Aisha) on the authority of Ibn Shihab with the same chain of transmitters (and the words are): Safiyyah bint Huyayy, the wife of Allah’s Apostle (may peace be upon him), entered the period of menses at the occasion of the Farewell Pilgrimage after she had performed Tawaf Ifada in the state of cleanliness; the rest of the Hadith is the same.
