Reading the whole Quran is one of the best good deeds a Muslim can do. Also, it is a great means of spiritually recharging and lifting up the heart. Blessings and reward for reading whole Quran are countless.
Hence, a good practicing Muslim should learn and recite as much of the Qur’an as he/ she can.
Responding to your question, Dr. Mohammad Qatanani, Professor at the Islamic American University and Imam of the Islamic Centre of Passaic County in New Jersey stated,
Reciting the Qur’an is the best act of worship after the obligations. Indeed, the Qur’an will be a witness either for or against you according to your relationship with it.
`Uthman (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) said, “The best of you are the ones who learn the Qur’an and teach it to others.” (Al-Bukhari)
