What is the ruling on praying in a mosque built with stolen government funds, and on land belonging to the government without its consent, knowing that the area is in dire need of this mosque?

Prayer in a mosque built with materials stolen from the state and on land belonging to it is valid, because these properties are public funds and it is permissible to spend them on building mosques. It would have been better for the one who built the mosque to acquire the land and money through legitimate means.
