Is it permissible to listen to the voice of a non-mahram woman singing, when it is merely a recording and she is not physically present, and the lyrics are not provocative?

It is impermissible for a man to listen to the singing of a woman who is not his mahram, even if it is without musical instruments or outside a singing gathering. This is because singing often involves softening and beautifying the voice and a lilt in speech, which can arouse desires. The voice of a non-mahram woman is not inherently awrah (nakedness), but it is forbidden to derive pleasure from listening to it because it leads to temptation. The Quran prohibits a woman from striking her feet so that her hidden adornments become known, so it is even more imperative to forbid listening to her softened and melodic singing voice. Forbidden listening is considered a precursor to zina (fornication/adultery), as stated in the noble hadith: "The zina of the ears is listening." The prohibition against a woman being alluring in her speech when addressing men is mentioned in the Holy Quran, so that he in whose heart is a disease may not covet.
