He asking about the proper Islamic way to celebrate weddings
Question

                What do suggest regarding an Islamic wedding party? I do not want any sin to be committed in this party, i.e. music, etc. but of course we want it to be delightful, we do not want the guests to feel bored.
Praise be to Allah.Celebrating weddings is a 
    celebration that is prescribed in sharee’ah, because it is a great blessing 
    from Allaah, Who has enabled the couple to find a means of happiness and a 
    way to achieve modesty and chastity. People have always expressed their joy 
    for this blessing since ancient times and they still do so today, and that 
    takes various forms and involves different customs in different societies 
    and countries. 
The aim of Islamic 
    sharee’ah is not to put pressure on people with regard to their customs or 
    try to make them follow only one custom, rather studying sharee’ah will show 
    that with regard to customs the matter is broad in scope and in principle 
    customs are permissible, with some limits and guidelines. 
The Muslim is recommended 
    to follow the customs of his people and he is forbidden to go against them, 
    so long as they do not go against the rulings of sharee’ah or cause any 
    hardship or embarrassment to people. The scholars ruled that it is 
    recommended to be similar to the people in their customs by analogy with the 
    ruling that it is recommended to be similar to them in dress. There is a 
    hadeeth concerning that which forbids being different from people in dress 
    so that one becomes known among people for the way he dresses. It was 
    narrated that Ibn ‘Umar (may Allaah be pleased with him) said: The Messenger 
    of Allaah  (peace and blessings of Allaah be upon him) said: “Whoever 
    wears a garment of fame and vanity, Allaah will clothe him in a garment of 
    humiliation on the Day of Resurrection.”  
Narrated by Ibn Majaah 
    (3606); classed as hasan by Shaykh al-Albaani in Saheeh Ibn Majaah. 
Fame and vanity in clothing 
    means wearing something that is extraordinarily expensive or extraordinarily 
    ragged. The salaf disliked both kinds of standing out: wearing expensive 
    clothing or wearing ragged clothing. 
It says something similar 
    in Majmoo’ al-Fataawa by Ibn Taymiyah (22/138). 
Shaykh Ibn ‘Uthaymeen (may 
    Allaah have mercy on him) said in al-Sharh al-Mumti’ (6/115): 
We must highlight this 
    point, that  going along with customs so long as they are not haraam is the 
    Sunnah, because going against customs is a kind of vanity, and the Prophet 
     (peace and blessings of Allaah be upon him) forbade the dress of fame 
    and vanity, so that which goes against customs is also forbidden. End 
    quote. 
Hence we advise you to hold 
    a wedding celebration and we ask Allaah to bless it. You should do it in 
    accordance with the custom and tradition of people in your country, and you 
    should not try to cast off all of their customs. All that you have to do is 
    reject and avoid those customs that are haraam, such as using music – apart 
    from the daff – and mixing between men and women. For more information 
    please see question no. 11446. 
There are many more things 
    that are permissible – praise be to Allaah – than those that are haraam. 
    Singing that is not accompanied by music, making food, bringing people 
    together, wearing adornments are all things that are permitted by sharee’ah, 
    so use whatever of those things you think is appropriate and that people like and ask Allaah to guide you in all of that. 
And Allaah knows best.
