All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
There is no clear text in the Quran about the prohibition of musical instruments, however, there are some verses about which the interpreters of the Quran stated that they are evidence about their prohibition, among which is the Saying of Allaah (which means): {And of the people is he who buys the amusement of speech to mislead [others] from the way of Allaah without knowledge and who takes it [i.e. His way] in ridicule. Those will have a humiliating punishment.}[Quran 31:6] The expression ‘the amusement of speech’ in the verse was interpreted to mean musical instruments and singing. Also, the Saying of Allaah [addressing Iblees] (which means): {And incite [to senselessness] whoever you can among them with your voice…}[Quran 17:64], was interpreted to mean singing and musical instruments.
Indeed, we have already issued Fataawa 81545 and 81239 clarifying that musical instruments are forbidden, so please refer to them.
As regards the ruling on dancing, if it is men dancing with non-Mahram women, or a woman dancing in a way that non-Mahram men can see her, then there is no doubt that this is forbidden for a Muslim. With regard to a woman dancing for her husband in a way that no one can see her, or a woman dancing in front of women in a way that men cannot see her, or men dancing without behaving like women, then this is permissible as long as this is not accompanied by a forbidden matter, like consuming intoxicants and music; for more benefit, please refer to Fatwa 81604.
As for the impermissibility of a Muslim eating with a non-Muslim in the same utensil, then this is not correct; rather, it is permissible to eat and drink with a non-Muslim even in one utensil provided that the food is lawful and provided that it is not linked to forbidden matters.
For more benefit, please refer to Fatwa 84761.
