I said: O Messenger of Allah, I think that Safiyya will detain us [prevent us from departing]. He said: What is the matter with her? I said: She has menstruated. He said: Had not she done Al-Ifadah circumambulation? I said: Yes, but she has got her menses after that. He said: So there is no detaining for you, and he departed with her.
