10)  The Houses in which the Qur’an is Recited Become Illuminated to the Inhabitants of the Heavens

Al-Bayhaqī has reported on the authority of ʿĀʾisha (R) that the Prophet (PBUH) said:  “The houses in which Qur’an is recited glow to the inhabitants of the Heavens the way in which the stars glow to the inhabitants of the earth.”

Al-Ḥakīm al-Timidhī reports on the authority of Abū Hurayra (R) and Abū Dardāʾ (R), “The houses of the believers are as lanterns in front of the Throne [of God].  It is recognized by the inhabitants of the seven Heavens.  They say: ‘This light emanates from the homes of the believers who recite the Qur’an.’”

11)  Recitation of the Qur’an Purifies the Heart

Al-Bayhaqī relates in Shuʿab al-īmān on the authority of Ibn ʿUmar (R) saying, “The Messenger of God (PBUH) said: ‘This heart rusts as iron rusts when exposed to water.”  It was asked: ‘O Messenger of God what is its purifier?’  He said: ‘An abundant remembrance of death and recitation of the Qur’an.’”
