"The head of the Messenger of Allah (ﷺ) would rest in the lap of one of us when she was menstruating, and he would recite Qur'an."
Sunan an-Nasa'i Book 3, Hadith 33
← Previous Hadith "I would drink when I was menstruating, then I would hand it to the Prophet (ﷺ), and he would put his mouth where mine had been and drink. And I would nibble at a bone on which some bits of meat were left when I was menstruating, then I would give it to the Prophet (ﷺ) and he would put his mouth where my mouth had been."

Sunan an-Nasa'i Book 3, Hadith 32 Next Hadith → "A woman asked 'Aishah: 'Should a menstruating woman make up the Salah she misses? She said: 'Are you a Haruri? We used to menstruate during the time of Allah's Messenger (ﷺ) but we did not make up the missed Salah nor were we commanded to do so.'"

Meaning are you one of the Khawarij. Harura is a place associated with a group of the Khawarij.
