In this paper, the Levy singing sound given over sin and minstrel's song voice introduced to the issue of religious veneration and lahvy Play only use in specific instances, such as forbidden gambling in the religion. Also the author prove that absolute prohibition of immoral and frivolous singing means singing voice commensurate with frivolous gatherings is not fixed in the Islamic law. In this regard, the author uncovered the historical misconception that the expression of Sheikh Ansari occurred  in the song issue and believe that he just focused on  the minstrel's song (not lahvy voices) as the subject of playing(Qena). Finally the author believe that forbidden playing is not accompanied with the lahvy voices according to it's famous meaning.
