What is the ruling on a Muslim abandoning the Qur’an, and what is the recompense for one who abandons it?

Abandoning the Qur’an is Islamically prohibited, and a Muslim must recite it and act upon it. This abandonment has various forms, including: forsaking belief and affirmation in it, neglecting its contemplation and understanding, failing to act upon it by obeying its commands and shunning its prohibitions, and becoming preoccupied with other things instead of it. The recompense for abandoning the Qur’an varies according to the type of abandonment. Some forms lead to disbelief (such as forsaking belief and affirmation), while others constitute a sin (such as failing to act upon it while still maintaining faith).
