Do I become kafir if I maintain half of the Quran and half not?

It is not for anyone to judge whether someone is a kafir (disbeliever) based on their level of knowledge or practice of the Quran. Only Allah knows what is in a person's heart and their true intentions. It is important to strive to learn and understand the Quran to the best of one's ability and to continuously seek knowledge and guidance from it. It is never too late to start learning and practicing more of the Quran, and Allah is always ready to forgive and guide those who sincerely seek His guidance.

According to the majority of Islamic scholars, maintaining half of the Quran and not the other half does not make one a kafir (non-believer). However, it is a grave sin and a serious shortcoming in one's faith.

Maintaining the Quran means believing in its message, reciting it regularly, and implementing its teachings in one's life. Leaving out half of it suggests a lack of understanding, commitment, or belief in its entirety.

The Quran is considered the complete and final revelation of God to humanity, and it is incumbent upon all Muslims to believe in its entirety. Neglecting a significant portion of it shows a lack of reverence and gratitude for God's guidance.

Therefore, while not maintaining half of the Quran does not automatically make one a kafir, it is a matter of great concern and should be addressed immediately through repentance, seeking knowledge, and striving to fulfill one's religious obligations fully.
