Is it permissible to collect money to hold parties in the mosque and call it charity?

The mosque must be kept free from anything that is unfitting for it, such as raising voices and idle chatter. This is usually present in parties, therefore, it is not appropriate to hold them in mosques. It is forbidden to hold them if they result in defiling the mosque or inconveniencing the worshippers, because mosques were built for worship. Collecting money to hold parties in mosques is an innovation (bid'ah). However, collecting money to feed the poor and comfort the needy is a good deed and a charity.
