Sura 48 Al-Fath (The Victory), aya 22

1. وَلَوْ قَاتَلَكُمُ الَّذِينَ كَفَرُوا لَوَلَّوُا الْأَدْبَارَ ثُمَّ لَا يَجِدُونَ وَلِيًّا وَلَا نَصِيرًا

   And if those (Makkans) who disbelieve had fought you, they would have turned their backs (in flight). Then they would not find a protector or a helper.

   48:22
