quran:48:22

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.  

And if those who disbelieve had fought you, at al-Hudaybiyya, they would have turned their backs ˹to flee˺ — then they would not have found any protector, to guard them, or helper.
القرآن:٤٨:٢٢

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

{ولو قاتلكم الذين كفروا} بالحديبية {لولّوا الأدبار ثم لا يجدون وليا} يحرسهم {ولا نصيرا}.
