اقرأ وتدبر الآية 383 من سورة سُورَةُ آلِ عِمۡرَانَ: إِنَّ الَّذِينَ كَفَرُوا بَعْدَ إِيمَانِهِمْ ثُمَّ ازْدَادُوا كُفْرًا لَنْ تُقْبَلَ تَوْبَتُهُمْ وَأُولَٰئِكَ هُمُ الضَّالُّونَ
إِنَّ الَّذِينَ كَفَرُوا بَعْدَ إِيمَانِهِمْ ثُمَّ ازْدَادُوا كُفْرًا لَنْ تُقْبَلَ تَوْبَتُهُمْ وَأُولَٰئِكَ هُمُ الضَّالُّونَ
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.
