Is there any way i can get the ABI and the source code of a contract without it being verified?

[ippy1997]

I'm trying to get the ABI of a smart contract or some way close to it , i don't have the source code because the contract is not verified all i have is the byte code , i tried to use some de-compilers and disassemblers but i didn't get much from doing that , all im trying to figure out if there is any way i can get the ABI or at least get close to it,

The reason why im trying to get the ABI because i want to decode input data that was in a transaction made with that unkown contract aka the contract without the source code and i want to know the data that was passed in or the arguments...if anyone knows how a good way i can do this let me now

feel free to recommend any good de-compilers , disassemblers or any effective ways or techniques i can use to kind of understand what the unknown code does.

THANKS
