Does the mourning period of a woman in 'iddah end with the delivery of her child, even if it is before four months and ten days?

Question:
Honorable Shaykh, may Allah grant you success. He says: If a woman is in 'iddah due to the death of her husband and she gives birth to her child a few nights after his death, is she required to observe mourning? Does the statement of the Prophet (peace and blessings be upon him) apply to her, regarding the four months and ten days?

Answer:
Mourning is attached to the 'iddah; it is attached to the 'iddah. If you are in 'iddah, you are in mourning. The 'iddah of a pregnant woman ends with the delivery of the child, even if it is a minute or an hour after the death. She exits the 'iddah. The term for pregnant women is that they give birth to their children, whether they are divorced or their husband has died. Even if the delivery is delayed for years, she remains in 'iddah. She does not exit the 'iddah until she gives birth, even if it is after four years. And mourning is attached to the 'iddah. Yes. That is it. And Allah the Exalted knows best, and may Allah send prayers and peace upon our Prophet Muhammad and upon his family and his Companions.
