A:
A woman whose husband dies is required to observe `Iddah for four months and ten days if she is not pregnant. Allah (Exalted be He) says:
And those of you who die and leave wives behind them, they (the wives) shall wait (as regards their marriage) for four months and ten (days)
The `Iddah starts from the date of the husband's death. If a woman intentionally does not observe her `Iddah, she is sinful and has to make Tawbah (repentance to Allah) and ask for Allah's Forgiveness. Regarding inheritance, she has right to inheritance if she is not divorced. In case a dispute arises about the inheritance, the matter should be referred to the Shari`ah Court.
