I am looking for an expression in English to wish all evil away from someone.
There are a handful of phrases in English that would qualify but they all depend on what you mean by "evil." If you mean a literal evil as in evil spirits, evil powers or evil forces than the only one I know of is:
This is a generic well wishing. More specific religious phrases, blessings and rituals are beyond the scope of this forum.
If you are less concerned about the supernatural and more concerned about random happenstance:
And if you are worried about people causing evil:
Three cases : a) You have have a religion ; then pray your God(s), or His (their) saints, if any, with your own words ; b) You have no specific creed, but are not too sure about possible supernatural powers : see a witch ; c) You are an atheist : in that case you know it is utterly useless, but nice to say him/her "all the best", for instance ; at least, it is certified to be harmless.
