Is the questioner's objection to some Sharia matters considered disbelief (kufr) that necessitates the annulment of her marriage? And would her previous years of marriage in this state be considered zina (fornication/adultery)? And must an apostate's marriage be annulled even if they repent before the annulment? And what is the ruling on her good deeds, such as prayer, fasting, and reciting the Quran, if she was a disbeliever?

Passing thoughts have no effect, and there is no harm in asking questions to inquire about wisdom, provided there is submission to the Sharia. If the dislike of Sharia rulings refers to the burden a Muslim finds while still submitting, this does not harm its owner. However, if it means dissatisfaction and doubt in them, then it is disbelief.

A Muslim should accept the rulings of Sharia with contentment and submission, then seek to understand their wisdom. If one of the spouses apostatizes, the marriage becomes null. However, if they repent and return to Islam before the expiry of the waiting period (iddah), they remain on the original marriage. Cohabitation during the state of apostasy due to ignorance is not considered zina (unlawful sexual intercourse), and the child is attributed to them. Good deeds from a disbeliever are not accepted until they repent and return to Islam.
