وَلَوْ قَاتَلَكُمُ الَّذِينَ كَفَرُوا لَوَلَّوُا الْأَدْبَارَ ثُمَّ لَا يَجِدُونَ وَلِيًّا وَلَا نَصِيرًا
[48:22]
And if those who disbelieve fight with you, they would certainly turn (their) backs, then they would not find any protector or a helper.
If the Unbelievers should fight you, they would certainly turn their backs; then would they find neither protector nor helper.
And if those who disbelieve join battle with you they will take to flight, and afterward they will find no protecting friend nor helper.
