Just for you I've found more proof.

And of mankind is he who purchases idle talks (i.e. music, singing) to mislead (men) from the path of Allaah…” [Luqmaan 31:6]

Al-Hasan al-Basri (may Allaah have mercy on him) said: this aayah was revealed concerning singing and musical instruments (lit. woodwind instruments). (Tafseer Ibn Katheer, 3/451).

“[Allaah said to Iblees:] And befool them gradually those whom you can among them with your voice (i.e. songs, music, and any other call for Allaah’s disobedience)…” [al-Israa’ 17:64]

“Do you then wonder at this recitation (the Qur’aan)?

And you laugh at it and weep not,

Wasting your (precious) lifetime in pastime and amusements (singing)”

[al-Najm 53:59-61]

Al-Albaani (may Allaah have mercy on him) said: The four madhhabs are agreed that all musical instruments are haraam. (al-Saheehah, 1/145).

I need to know, what more proof do you need? I wouldn't dare go against the four Imams in any matter. When the Quran, Sunnah and the Imams have all declared that the musical instruments are haraam, I don't understand how you can continue to deny this.
