Does a non-Muslim woman have to observe the 'iddah (waiting period) if she embraces Islam while married to a non-Muslim, knowing that she is in her postpartum period?

A recently converted Muslim woman must hasten to embrace Islam, which is the religion of truth. After her conversion, she must refrain from her non-Muslim husband, separate from him in dwelling, and begin her waiting period (iddah).

The majority of scholars agree that her iddah is like that of a divorced woman: three menstrual cycles for those who menstruate, three months for those who have reached menopause, and until she delivers her child for pregnant women. The period of postpartum bleeding (nifas) is not counted as part of the iddah; the iddah begins after the nifas ends.

If the husband converts to Islam during the iddah period, their marriage remains valid without the need for a new contract. However, if the iddah ends and the husband has not embraced Islam, some jurists consider the marriage annulled. The correct view, which was favored by Sheikh al-Islam Ibn Taymiyyah and Ibn al-Qayyim, is that if they agree to reconcile, it is permissible for them to do so based on the original contract without the need for a new one, unless the woman has married someone else. This is supported by the hadith of the Prophet (peace be upon him) returning his daughter Zaynab to her husband Abu al-As with her original marriage after he embraced Islam.
