The Noble Qur'an - Luqman 31:6
And of mankind is he who purchases idle talks (i.e. music, singing, etc.) to mislead (men) from the Path of Allah without knowledge, and takes it (the Path of Allah, the Verses of the Qur'an) by way of mockery. For such there will be a humiliating torment (in the Hell-Fire).
Hadith - Bukhari (#787) [Also related by Tabari]
Sa'id ibn Jbayr reported that Ibn 'Abbas said about the verse: "And of mankind is he who purchases idle talks" (31:6), that, "ldle talks means singing and the like."
The Noble Qur'an - Al-Isra 17:64
"And Istafiz [literally means: befool them gradually] those whom you can among them with your voice (i.e. songs, music, and other call for Allah's disobedience)..."
Hadith - Bukhari 7:494
Narrated Abu 'Amir or Abu Malik Al-Ash'ari that he heard the Prophet saaws saying,
"From among my followers there will be some people who will consider illegal sexual intercourse, the wearing of silk, the drinking of alcoholic drinks, and the use of musical instruments as lawful. And (from them), there will be some who will stay near the side of a mountain, and in the evening their shepherd will come to them with their sheep and ask them for something, but they will say to him, 'Return to us tomorrow.' Allah will destroy them during the night and will let the mountain fall on them, and Allah will transform the rest of them into monkeys and pigs and they will remain so till the Day of Resurrection."
The Noble Qur'an - An-Najm 53:57-62
The Day of Resurrection draws near, None besides Allah can avert it, (or advance it, or delay it). Do you then wonder at this recital (the Qur'an)? And you laugh at it and weep not, Wasting your (precious) lifetime in pastime and amusements (singing, etc.). So fall you down in prostration to Allah, and worship Him (Alone).
So you say the Quran doesn't prohibit music and dance. It clear you don't know your Quran as well as you should, or are you covering up some of it's absurdities?
Hadees-e-Qudsi (19:5) The Prophet said that Allah commanded him to destroy all the musical instruments, idols, crosses and all the trappings of ignorance. Allah said that if a man took even a mouthful of wine, He would make him drink the same quantity of pus of the wounds of the people in Hell.
