وَلَوۡ قَٰتَلَكُمُ ٱلَّذِينَ كَفَرُواْ لَوَلَّوُاْ ٱلۡأَدۡبَٰرَ ثُمَّ لَا يَجِدُونَ وَلِيّٗا وَلَا نَصِيرٗا ٢٢
Wa law qātalakumul-ladhīna kafarū lawallawul-adbāra thumma lā yajidūna waliyyaw wa lā naṣīrā.
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.
