They will not harm you except for [some] annoyance. And if they fight you, they will show you their backs [i.e., retreat]; then they will not be aided.

Tafsir
If they are against you they will not harm you, O believers, in your belief, or in yourselves, except through their words: criticising your faith and making fun of you and so on. Also, if they fight you they will flee from you in defeat, and will never be victorious over you.
