Music is not allowed in Islam
It is prohibited, on the basis on Holy Quran and Authentic Hadith.
People who say, it is allowed do not have any strong and authentic evidence or reference.
Allah says in Holy Quran ( in Surah Luqman ):
“And of mankind is he who purchases idle talks (i.e. music, singing) to mislead (men) from the path of Allah…” [Luqman 31:6]
According to Great Scholars of Islam idle talks refers to music, singing...
The scholar of the ummah, Ibn 'Abbas (may Allah be pleased with him) said: this means singing . Mujahid (may Allah have mercy on him) said: this means playing the drum (tabl). (Tafsir al-Tabari, 21/40)
Al-Hasan al-Basri (may Allah have mercy on him) said: this ayah was revealed concerning singing and musical instruments (lit. woodwind instruments). (Tafsir Ibn Kathir, 3/451)
