What did the Prophet Muhammad (saw) say about those who learn and recite the Quran by heart?
 Narrated Aisha:                     The Prophet said, "Such a person as recites the Qur'an and masters it by heart, will be with the noble righteous scribes (in Heaven). And such a person exerts himself to learn the Qur'an by heart, and recites it with great difficulty, will have a double reward."
