He asking about the proper Islamic way to celebrate weddings

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.
