It is permissible for you to spend
the rest of the money raised for furnishing the Masjid in furnishing another Masjid if the first one does not need anything anymore. However, it is impermissible to spend the money on anything else other than furnishing Masjids, as this is considered spending it in a way other than the donors intended.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
