question #2 Sahih Muslim 104a, Book 1, Hadith 193 : How does Islam view excessive expressions of sorrow such as wailing or tearing garments?

I have no concern with one with whom the Messenger of Allah (ﷺ) has no concern, Verily the Messenger of Allah (ﷺ) has no concern with that woman who wails loudly, shaves her hair and tears (her garment in grief).
