The Book of Pilgrimage (Kitab Al-Hajj)
Muslim :: Book 7 : Hadith 3064
'A'isha (Allah be pleased with her) said to the Messenger of Allah (may peace be upon him): Messenger of Allah, Safiyyah bint Huyayy has entered the state of menses, whereupon Allah's Messenger (may peace be upon him) said: Perhaps she is going to detain us. Has she not clicumambulated the House along with you (i. e. whether she has not performed Tawaf Ifada)? They said: Yes. He said: Then they should set out.
