Does the validity of a man's marriage contract affect his cursing God Almighty and praying without Wudu intentionally and out of shyness from people?

Abusing God is apostasy and a renunciation of Islam. Praying after the abuse is a return to Islam. Praying without ablution (wudu') or being negligent in prayer are among the major sins, but they do not expel a Muslim from Islam. However, repentance is obligatory, and one must make up for missed prayers. The marriage contract is valid if it fulfills the conditions, and the previous disbelief of the husband does not affect it if he returns to Islam.
