48:22
وَلَوْ قَـٰتَلَكُمُ ٱلَّذِينَ كَفَرُوا۟ لَوَلَّوُا۟ ٱلْأَدْبَـٰرَ ثُمَّ لَا يَجِدُونَ وَلِيًّا وَلَا نَصِيرًا
walaw qātalakumu alladhīna kafarū lawallawū l-adbāra thumma lā yajidūna waliyyan walā naṣīran
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.

If the disbelievers had fought against you, they would have taken flight and found no one to protect or support them:

And if those who disbelieve fight against you, they certainly would have turned their backs; then they would have found neither a Walî (protector, guardian) nor a helper.
