This sentence was not said by Confucius. I did a little research about this.
各人自扫门前雪，莫管他人瓦上霜
-----------------------------------------
【注音】：gè rén zì sǎo mén qián xuě，mò guǎn tā rén wǎ shàng shuāng
【解释】：莫管：不要管。比喻不要多管闲事。
【出自】：明·张凤翼《灌园记·后识法章》：“进去罢，各人自扫门前雪，莫管他家瓦上霜。”
你怎么说这句话的普通话呢？
“Don’t complain about the snow on your neighbor’s roof when your own doorstep is unclean.”
― Confucius
Hello, I'm from Taiwan and I wanna share a very famous slogan from a Gillette CF in Taiwan which might fit into the modern version of the saying.
"刮別人鬍子前，先把自己鬍子刮乾淨。"
For your reference!

1.嚴以律己，寬以待人
<em>2.刮別人</em><em>鬍子前</em>，先把自己刮乾淨
都是類似的意思
孔子不但沒說過這句話
而且也不會勸人不要多管閒事
"莫管他人瓦上霜" 是徹底誤解孔子思想
論語 子路第十三
子曰：「苟正其身矣，於從政乎何有？不能正其身，如正人何？」
孔子說：「能真正端正自己, 那從政有何困難.若不能端正自己, 又如何端正別人?」
