Ruling on organizing festivals that involve music and singing
Question

                What is the ruling on establishing festivals in which actors, singers and poets are invited to come from the country of the festival or abroad. 
Please clarify the ruling on the following: 

Firstly: What is the ruling on arranging such parties, knowing that they are about singing and music all or most of the time?
 
Secondly: what is the ruling on inviting, encouraging and spending on such festivals? And what is the ruling on bringing non-Muslim singers, spending on them, welcoming them, feeling happy for their attendance and listening to them?

Thirdly: what is the ruling on those who attend such festivals and listen to them?.
Praise be to Allah.
    It is haraam for the Muslim to organize parties or festivals 
    that include haraam things, such as singing and music, mixing of men and 
    women, and bringing charlatan magicians, because there is a great deal of 
    shar’i evidence that indicates that such things are haraam and they are 
    causes of people falling into that which Allaah has forbidden of immoral and 
    evil actions. Allaah warns those who want immorality to be spread among the 
    believers and promote that, and He has prepared a painful punishment for 
    them. Allaah says (interpretation of the meaning): “Verily, those who 
    like that (the crime of) illegal sexual intercourse should be propagated 
    among those who believe, they will have a painful torment in this world and 
    in the Hereafter” [al-Noor 24:18]. Once it is established that these 
    parties and festivals are haraam, it is also haraam to attend them, because 
    they are a waste of time and money in things that are not pleasing to 
    Allaah, and they are cooperating in sin and transgression, and Allaah says 
    (interpretation of the meaning): “Help you one another in Al‑Birr and 
    At‑Taqwa (virtue, righteousness and piety); but do not help one another in 
    sin and transgression. And fear Allaah. Verily, Allaah is Severe in 
    punishment” [al-Maa’idah 5:2]. And in a hadeeth the authenticity of 
    which is agreed upon, the Prophet  (peace and blessings of Allaah be 
    upon him) forbade wasting money. 

    And Allaah is the source of strength. May Allaah send 
    blessings and peace upon our Prophet Muhammad and his family and companions.
