Does insulting the wife's parents, and Allah and His religion, and the fact that the contract was concluded by an officiant who applies man-made laws, affect the validity of the marriage? And does the lack of commitment to prayer, and the spouses' uttering offensive words against Allah and His religion, as well as swearing by other than Allah, affect the validity of the contract and necessitate its renewal? And is it obligatory to verify the wife's divorce from her former fiancé, with whom she had not consummated the marriage, for fear that this might affect the validity of the current contract?

Cursing the Lord or religion is an act of disbelief (kufr) and apostasy (riddah). The obligation (takleef) is not lifted by anger unless the person does not know what he is saying.

The conclusion is that there is no excuse for the girl's father for the cursing he committed, nor for you and your wife.

An apostate is not fit to be a guardian (wali) in marriage, and a marriage in which he acts as a guardian is invalid.

It is not possible to definitively confirm the validity of the marriage in this case. It is preferable to consult a Sharia court or Islamic centers to ascertain what was uttered and whether it entails apostasy.

One who abandons prayer commits a grave sin, and some scholars have considered it an act of disbelief.

You are not required to seek a divorce for the woman if the contract has been annulled or the husband has divorced.

The work of the marriage registrar (ma'thoun) under man-made laws does not affect the contract if it was validly concluded, and it is not mandatory for the contract to be performed through a registrar.
