I don’t want to create any problems for anyone. But do I have the right to interfere in this matter and warn this new person?
Answer
In principle, it is a moral responsibility to serve the oppressed and
deceived.
Therefore, if you fear the person in reference will be oppressed and
deceived, you may inform him with the intention of saving him.
and Allah Ta’ala Knows Best
