In Sweden you can allocate some of your already paid taxes to a masjid, in my case I signed a contract to do it for an ikhwani and deviant one and I dont know what tehy use the money for, maybe they use it for both the masjid and deviance. Is it wajib for me to annul this contract?

Allah knows best in regards to what you can do, but if you are able to benefit those who are upon the sunnah then without a doubt you should prioritize that.
