Literal translation:
Who among you is without sin, threw a stone first
It's a famous Bible quote, which has many translations who fit the context better, like "He who is without sin among you, let him be the first to throw a stone at her"
I'm sure you'll find many interpretations online that fit anything you need.
I hope this helps, even though English isn't my first language :)
