“Abu al-Hassan, al-Rida’ (a.s.), has said, ‘If one keeps his soul clean of al-Ghina’ (music (and singing)), Allah, most Majestic, most Glorious, commands the winds to move a tree in the garden (paradises). From this tree a sound is heard the like of which is never heard, and those who fail to keep their souls clean of al-Ghina’ (music (and singing)) will not be able to hear it.’”
