The Messenger of Allah said: "Whoever reads a letter from the Book of Allah (the Qur'an), then for him one good deed, and one good deed is rewarded with ten times as much." (HR. At-Tirmidhi). As for the reward for those who listen to the recitation of the Qur'an, the certainty of the reward is known only to Allah Ta'ala.
