Abu Musa said he fell unconscious and an Umm Walad of his wept. When he woke up, he asked her: "Have you not heard what the Messenger of Allah said?" She said: "He said: 'He is not one of us who raises his voice in lamentation, shaves his head, or rends his garments.""
Sunan an-Nasa'i Book 21, Hadith 48
