What is the definition of ghina (singing)? What constitutes unlawful singing and music? What if it was used in the celebrations of Islamic events like Eid al-Ghadir and the birth anniversaries of the infallible Imams (pbut)?
Ghina (singing) is speech that is characterized as amusement and expressed in melodies that are known as such by people of entertainment and play. This is established according to common view (urf) and it is impermissible to sing, listen to it, or earn through it. It is also not permitted to recite the Holy Quran, supplications, praise of Ahl al-Bayt, and anything similar with such melodies, and even non-amusement speech based on obligatory precaution. And, there is no problem in something that is doubted to be ghina or falls into that category. As for music, like singing, it is prohibited if it is suitable for gatherings of entertainment and play, like playing the trumpet. As for other music, like the type used by the army, at a funeral or classical music, it is permissible, although based on a recommended precaution it should be avoided.
