Since men and women are the same in Allah’s eyes either Allah doesn’t let the widow follow a self torturing custom like restricted to certain freedoms or makes both the husband and wife do it incase of their spouses death. Example: Wearing only white clothes, wearing only black, and other oppressive rituals against freedom
