A nasheed (Arabic: singular , plural , meaning: "chants") is a work of vocal music, partially coincident with hymns, that is either sung a cappella or with instruments, according to a particular style or tradition within Islam. Nasheeds are popular throughout the Islamic world. The material and lyrics of a nasheed usually make reference to Islamic beliefs, history, and religion, as well as current events. Scholars on instruments The founders of all four of the major madhabs – Islamic schools of thought – as well as many other prominent scholars, have debated the legitimacy and use of musical instruments. For instance, according to the Hanafi school of thought, associated with the scholar Abu Hanifa, if a person is known to play musical instruments to divert people from God, their testimony is not to be accepted. According to the widely acknowledged book of authentic hadiths Sahih al-Bukhari of Sunni scholarship, Muhammad taught that musical instruments are sinful: Abu 'Amir or Abu Malik Al-Ash'ari [a companion of Muhammad] said that he heard Muhammad 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." There is also evidence for music being permitted in the same book. Aisha said: Abu Bakr came to my house while two small Ansari girls were singing beside me the stories of the Ansar concerning the Day of Buath. And they were not singers. Abu Bakr said protestingly, "Musical instruments of Satan in the house of Allah's Messenger!" It happened on the `Id day and Allah's Messenger said, "O Abu Bakr! There is an `Id for every nation and this is our `Id." A few historical Islamic scholars such as Imam Al-Ghazali have also said that musical instruments may be used as long as the songs are not promoting that which is Haraam. Modern interpretations A
