All of the holy books that came before the Qur'an are clear that the malaikah (angels) sing, the most beautiful music such as cannot even be imagined by the human ear. These verses have been confirmed by people who have died and come back to report malaikah singing and it's purity and clarity.
Also it is well known that King David played the harp, and King Solomon composed the Song of Songs. Also in other holy books, it says that Allah specifically commanded the Jews that they are to make music in
2 Chronicles 29:25 And he set the Levites in the house of the LORD with cymbals, with psalteries, and with harps, according to the commandment of David, and of Gad the king's seer, and Nathan the prophet: for so was the commandment of the LORD by his prophets.
The Question is: Why is Music considered forbidden in Islam when it is not in the previous revelations given to the Jews and Christians?
