While some Muslims mention a few Quranic verses that supposedly implicitly ban music, there are several hadiths that explicitly do so.
Prohibition of music is recorded in many authentic Ahadith.
Narrated Abu Malik Al-Ashari: The Messenger (peace be upon him) of Allah said, "Some people of my Ummah will drink wine, calling it by other than its real name, merriment will be made for them through the playing of musical instruments and the singing of lady singers. Allah will cleave the earth under them and turn others into monkeys and swines.” [Ibn Ma'jah Vol.5 Hadith No.4020]
Narrated Abu Amir or Abu Malik Al Ashari that he heard the Prophet (peace be upon him) 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 there will be some people 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 He will transform the rest of them into monkeys and pigs and they will remain so till the Day of Resurrection." [Sahih Al-Bukhari Vol.7 Hadith No.5590]
Prophet (peace be upon him) further mentions, “Music grows hypocrisy in the heart just as water causes crops to grow.” (Bayhaqi vol.10 pg.222)
However, there are some Ahadith which indicate that it is permissible to beat the ‘daff’ i.e. the tambourine (which is open on one side and covered on the other).
Narrated Urwa on the authority of Aisha “On the days of Mina, (11th, 12th, and 13th of Dhul-Hijjah) Abu Bakr came to her while two young girls were beating the tambourine (daff) and the Prophet (peace be upon him) was lying covered with his clothes. Abu Bakr scolded them. The Prophet uncovered his face and said to Abu Bakr, 'Leave them, for these days are the days of Eid and the days of Mina.' [Sahih Al-Bukhari Vol.2 Hadith No.987]
Narrated Ar Rabi (the daughter of Muawwidh bin Afra): “After the consummation of my marriage, the Prophet came and sat on my bed as far from me as you are sitting now, and our little girls started beating the tambourines (daff) and reciting elegiac verses mourning my father, who had been killed in the battle of Badr. One of them said, ‘Among us is a Prophet (peace be upon him) who knows what will happen tomorrow.’ On that the Prophet (peace be upon him) said, "Leave this (saying) and keep on saying the verses which you had been saying before." [Sahih Al-Bukhari Vol.7 Hadith No.5147]
Therefore from the above evidence it is concluded that the use of musical instruments in general is forbidden in Islam, with the exception of the 'Daff'. Furthermore, singing without music is permissible on condition that the song does not contain anything un-Islamic in it. For example, it must not be a song that is normally played with music, it must not have a tone of a music song. There must not be any immoral contents in the song. Poetry (She’r) and Nazms (songs) are meant to refresh a person’s Imaan and enhance one’s love for Islam, Allah and His Rasul [sallallaahu alayhi wasallam
