"r40.2 (Nawawi:) It is unlawful to use musical instruments—such as those which drinkers are known for, like the mandolin, lute, cymbals, and flute—or to listen to them. It is permissible to play the tambourine at weddings, circumcisions, and other times, even if it has bells on its sides. Beating the kuba, a long drum with a narrow middle, is unlawful (Mughni al-muhtaj ila ma'rifa ma'ani alfaz al-Minhaj (y73), 4.429-30). SINGING UNACCOMPANIED BY MUSICAL INSTRUMENTS r40.3 (Ibn Hajar Haytami:) As for listening to singing that is not accompanied by instruments, one should know that singing or listening to singing is offensive except under the circumstances to be mentioned in what follows. Some scholars hold that singing is sunna at weddings and the like, and of our Imams, Ghazali and 'Izz ibn 'Abd al-Salam say that it is sunna if it moves one to a noble state of mind that makes one remember the hereafter. It is clear from this that all poetry which encourages good deeds, wisdom, noble qualities, abstinence from this-worldly things, or similar pious traits such as urging one to obey Allah, follow the sunna, or shun disobedience, is sunna to write, sing, or listen to, as more than one of our Imams have stated is obvious, since using a means to do good is itself doing good (Kaff al-ra'a' 'an muharramat al-lahw wa al-sama' (y49), 2.273)."
