Are lights on the house of a Muslim family a sign of a wedding?

Yes, lights on the house of a Muslim family can be a sign of a wedding celebration, as many families decorate their homes with lights and other decorations to signify joyous occasions. However, it's important to note that such decorations can also be used for other celebrations or festivals. Therefore, while lights may indicate a wedding, they are not exclusively a sign of one. Context and local customs can also play a significant role in the meaning behind the decorations.
