This proverb comes from my native language (Georgian). It behaves like a warning, when it is used in reference to a person. It can be used, when you are giving a piece of advice to somebody, thus fulfilling your duty and obligation as a human being. So, from that moment forth, whether the other side will take your suggestions or recommendations into consideration, it is up to them to decide. You won’t have to deal with consequences of their decisions anymore, since you warned them that something might go wrong. Is there an idiom or proverb in English, similar to the above-mentioned one in meaning?
I’ve done my part.
to do one’s part.
to do what one is responsible for doing or is able to do
I've done my part, and now it's time for him to do his.
