Narrated by Sayyidah Aisha (may Allah be pleased with her) that the Prophet Muhammad (peace be upon him) said: The example of the person who recites the Qur'an and has memorized it is like that of the noble and righteous scribes (angels), and the person who recites the Qur'an repeatedly, though it is difficult for him, will have a double reward.
