Is a person rewarded for stopping the recitation of the Qur’an to reflect and learn, or to ponder a jurisprudential issue, or to rest so as not to get bored?

You are rewarded for engaging in dhikr (remembrance of God) or contemplating knowledge. Reciting the Quran is better than dhikr, but if your heart is more present during dhikr than during Quran recitation, then dhikr is better. If you feel bored with an act of worship and your heart finds greater rectification in another, then do that. Sheikh al-Islam was asked which of the two is better: reciting the Quran or dhikr? He replied that it varies depending on individuals and circumstances. If a person understands and ponders the Quran, then recitation is better for them. If not, and dhikr is more conducive to their focus, then dhikr is better. The seeker should not abandon their share of both; they should engage in dhikr until they feel bored, then transition to reciting the Quran with contemplation and reflection.
