﴿ إِنَّ ٱلَّذِينَ كَفَرُوا۟ بَعْدَ إِيمَٰنِهِمْ ثُمَّ ٱزْدَادُوا۟ كُفْرًۭا لَّن تُقْبَلَ تَوْبَتُهُمْ وَأُو۟لَٰٓئِكَ هُمُ ٱلضَّآلُّونَ ﴾

“Verily, as for those who are bent on denying the truth after having attained to faith, and then grow [ever more stubborn] in their refusal to acknowledge the truth, their repentance [of other sins] shall not be accepted: for it is they who have truly gone astray.”

(Lo! those who disbelieve) in Allah (after their (profession of) belief) in Allah, (and afterward grow violent in disbelief) do not waver in their disbelief: (their repentance will not be accepted) as long as they remain in that state. (And such are those who are astray) from guidance and Islam.
