Forsaking the Qur'an (Surah Al-Furqan 25: 30)

When The Messenger (Sallallahu Alayhi wa Sallam) would recite Qur'an to them (the idolators), they would talk nonsense or speak about something else, so that they would not hear it. This is a form of forsaking it and rejecting it, and not believing in it is the same as forsaking it, and not pondering its meanings and trying to understand it is the same as forsaking it, and not acting upon it and following its commandments and heeding its prohibitions is the same as forsaking it, and turning away from it in favor of poetry or other words or songs or idle talk or some other way is the same as forsaking it.

We ask Allah, the Most Generous, the Bestower of bounty, the One Who is able to do what He wills, to keep us safe from doing that which earns His wrath and to use us to do that which will earn His pleasure of preserving and understanding His Book, following its commandments night and day in the manner which He loves and which pleases Him, for He is Generous and Kind. Ameen
