Does the repentance of someone who has cursed Allah Almighty with grave sexual الفاظ (highly exalted is Allah above that) get accepted, especially if the cursing was intentional, and is it necessary to mention the الفاظ when repenting?

Cursing God and abandoning prayer are among the gravest sins. One who abandons prayer is worse than a thief or an adulterer, and, according to the majority of scholars, should be executed. Nevertheless, Allah accepts repentance from His repentant servant. Allah's forgiveness is not too great for any sin, even polytheism, in accordance with His Almighty saying: "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.'" Therefore, sincere repentance from all sins is obligatory, as is not despairing of Allah's mercy and maintaining prayer, for it restrains from indecency and evil.
