وَلَوْ قَاتَلَكُمُ الَّذِينَ كَفَرُوا لَوَلَّوُا الْأَدْبَارَ ثُمَّ لَا يَجِدُونَ وَلِيًّا وَلَا نَصِيرًا
Walaw qatalakumu allatheena kafaroo lawallawoo al-adbara thumma la yajidoona waliyyan wala naseeran
And if, fight you, those who disbelieve, surely they would turn the backs. Then not they would find any protector and not any helper.
And [now,] if they who are bent on denying the truth should fight against you, they will indeed turn their backs [in flight], and will find none to protect them and none to bring them succour:
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.
And if those who disbelieve fight with you, they will certainly turn (their) backs, then they will find no protector nor helper.
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.
