Ali 'Imran 3:111

لَن يَضُرُّوكُمْ إِلَّآ أَذًى ۖ وَإِن يُقَـٰتِلُوكُمْ يُوَلُّوكُمُ ٱلْأَدْبَارَ ثُمَّ لَا يُنصَرُونَ

Lan yaḍurrūkum illā adhan wa-in yuqātilūkum yuwallūkumu l-adbāra thumma lā yunṣarūna

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.
