The Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), said that he (peace and blessings be upon him) said: "The one who recites the Qur'an with skill is like the noble angels, and as for the one who recites the Qur'an and strives to memorise it while it is hard for him, he will have two rewards."
