Islam, as a perfect religion, had arranged all sides of human life. Including wedding. Wedding is something sacred. However, many people do not know what is allowed and what is forbidden in the wedding.
In Islam, announced the marriage, including the recommended. And included in the category announced the marriage of a festive wedding. But on this side, most people make mistakes. Whether intentional or not. Either because he did not know or because of ignorance.
What's mistake? that mistake is music. Enliven wedding with music is a mistake that is often not realized. Music is not allowed in Islam.
So like what is right? We can replace it with a song. Song of the marriage is allowed, provided not accompanied with music equipment, except for duff, -looks like tambourines-.
Kids Anasheed might be alternative. It's a simple song sung by kids. There are many choices. you can get it here.
