What is the ruling on listening to foreign music or singing whose words are not understood? And what is the wisdom behind its prohibition and its extent if it is deemed unlawful?

A group of scholars have reported a consensus on the impermissibility of listening to music and musical instruments. Singing accompanied by musical instruments is forbidden. The prohibition of music and listening to singing accompanied by it applies to everyone without distinction. Among the reasons for this prohibition is that singing breeds hypocrisy in the heart, and that it is a harbinger of immorality and the emblem of drunkards, transgressors, and disobedient people.
