As-Salam-u-Alaikum wa-rahmatullahi wa-barakatuh. All praise is to Allah.
a cousin of mine opened a online payment account on my name with credentials with my knowledge but i didnt know what he was going to do ( i knew that he maybe use it for gambling but he didn’t mention directlty) with it and he opened a betting account with my name and credentials ( i didnt give him permission to use it for betting and i had no knowledge or i can’t remember since it was more than 1.5 years ago) am i getting the major sin or any sin ? what should i do ? this was back when i didnt pray and drank and was muslim by name. he is lying to me i can tell but im not sure . and i have not invested in those accounts. he says he doens’t gamble anymore on that account. He might by lying i want to report this to every website but those are not my money in the betting or bank account. What should i do i told him also not to use them anymore but he may still continue to do these.

In the enquired scenario, you will not be sinful for the mere fact that your cousin may perpetrate impermissible acts using your credentials.
You may consider speaking to him in order to find out the reality of the situation and if he is involved in it, then to encourage him to stop, and with that, to write to these websites that your credentials are being used falsely.
