The female voice, according to Islam, is also included in the category of Satar, i.e. it has to be ‘concealed’ and NOT ‘revealed’. Since the female voice is an entity NOT to be displayed or advertised, it is NOT permissible for males to listen to women singing or even reciting the Quran.
When necessity demands that they have to speak to males then their speech should not be attractive, gently and alluring like the deliberate ‘lure’ put in speech by ‘trained’ women of the disbelievers. Recognizing the danger of allurement in the female voice, the Quran commands women thus:
"…then be not soft in speech, lest he in whose heart is a disease (of hypocrisy or evil desire for adultery, etc.) should be moved with desire, but speak in an honorable manner." (Al-Ahzab 33:32)
Van de Velde in his book Ideal Marriage, states:
"The tone-color of a voice, and the intonation of single word - and it may be word of no special meaning or association in itself - may excite incredible intensity of desire. The unique and precious significance that a woman’s voice can give to ‘you’ or ‘thou’ can suffice to overwhelm man’s power of endurance and control…"
Islam has, hence, FORBIDDEN its women to speak in a soft or "sexually" sweet tone. If anyone is aware of the springs of sex-psychology he will clearly see the justification for Islam’s restriction in this matter.
Islam COMMANDS the concealment of the female voice and prohibits its display in public, but television demands the contrary. Great use is made of the female voice on TV to advertise, to allure, to excite lust, and female singing with the accompaniment of music is most popular.
The importance of television programs, like the importance of all the mass media of the disbelievers, hinges on maximum exhibition of the female body and the female voice which have been subverted by the brutal culture of the unbelievers, to pamper the inordinate sexual desires of men who have no belief of Allah - of men who have no fear of Allah left in them.
