What is the ruling for a widow regarding Iddah? Is it allowed not to perform iddah for 4 months and 10 days for a young woman ? Some people say that if the woman steps out with the mayyat of the deceased husband then she is allowed NOT to do Iddah . Is it true ? If a woman does not do iddah, Isn't it a Sin ( gunah ) she is doing ?

Widow should perform iddah whether she has gone with her husband or not
