5. Singing and hypocrisy
The sixth Holy Imam, Imam Ja’far as-Sadiq (a.s.) said,
“Listening to music, songs and useless words cultivate hypocrisy in the heart, in the same way as algae grows in water.”
(al-KÄfi)
The same book, al-KÄfi mentions a tradition of Imam as-Sadiq (a.s.) that,
“Singing and music is a nest for the bird called hypocrisy.”
