No expiation for not observing Hidad

Q: My father died a long time ago, but my mother did not observe `Iddah (woman's prescribed waiting period after divorce or widowhood) Please advise whether she has to pay expiation or not, given that she is still alive.

A: A widow is obligated to observe `Iddah for four months and ten days following her husband's death. In case she is pregnant, her `Iddah ends when she delivers the baby. As your mother did not observe `Iddah in its proper time, either out of ignorance or otherwise, she does not have to pay expiation; she only has to make Tawbah (repentance to Allah), Istighfar (seeking forgiveness from Allah), and say Dhikr (Remembrance of Allah) frequently.
