Surah Ali 'Imran 3:111

لَن يَضُرُّوكُمْ إِلَّآ أَذًى ۖ وَإِن يُقَـٰتِلُوكُمْ يُوَلُّوكُمُ ٱلْأَدْبَارَ ثُمَّ لَا يُنصَرُونَ

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.

Translation: Saheeh International

Tafsir

They the Jews will not harm you O company of Muslims in any way except a little hurt with their tongues such as slander and threats; and if they fight against you they will turn their backs to you in retreat then they will not be helped against you but you will be helped against them.
