Is mocking God of a lesser degree than polytheism (shirk)? And is there a disbelief (kufr) from which repentance is not accepted, even before the death rattle? And is there anyone more disbelieving than Pharaoh, and could Pharaoh have been among the righteous if he had repented? And does mocking the Creator lead to a lack of guidance, and can its perpetrator marry?

Mocking God is a major act of disbelief (kufr akbar) that God does not forgive its perpetrator if they die upon it. However, if one repents from disbelief or major polytheism (shirk akbar) with sincere repentance, then God accepts their repentance and forgives all their sins, as stated in the verse: "Say, 'O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.'" (Quran 39:53). If one repents with sincere repentance, there is no impediment to their marriage to a Muslim woman. As for his marriage to a disbelieving woman, it is permissible even if he remains in his disbelief, but a Muslim is not permitted to solemnize their marriage contract. There may be those whose disbelief is even more severe than Pharaoh's, and there is no impediment to that.
