From Sahih Muslim (Hadith 3225):
A'isha (Allah be pleased with her) reported:We feared that Safiyyah might have entered the period of menses before performing Tawaf Ifada. Allah's Messenger (ﷺ) came to us and said: Is Safiyyah going to detain us? Thereupon we said: She has performed Tawaf Ifada. He (the Holy Prophet) said: Then there is no detention (for us) now
