‘A’isha told that Safiya began to menstruate on the night before yaum an-nafr and said, “It looks as if I shall detain you;” whereupon the Prophet said, “How unlucky and annoying you are!” He asked whether she had performed the circumambulation on the day of sacrifice, and on being informed that she had, he told her to set off. Bukhari and Muslim.
