One of the oaths which the Messenger of Allah (ﷺ) received from us about the virtue was that we would not disobey him in it (virtue): that we would not scratch the face, nor wail, nor tear the front of the garments nor dishevel the hair.
Sunan Abi Dawud Book 21, Hadith 43

She said: Yes. The narrator said: She then kept silence. When AbuMusa died, Yazid said: I met the woman and asked her: What did AbuMusa mean when he said to you: Did you not hear what the Messenger of Allah (ﷺ) and the you kept silence? She replied: The Messenger of Allah (ﷺ) said: He who shaves (his head), shouts and tears his clothing does not belong to us.
