Surah Al-Fath — Ayah 22 (48:22)
وَلَوۡ قَٰتَلَكُمُ ٱلَّذِينَ كَفَرُواْ لَوَلَّوُاْ ٱلۡأَدۡبَٰرَ ثُمَّ لَا يَجِدُونَ وَلِيّٗا وَلَا نَصِيرٗا ٢٢
English translation (Saheeh International)
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.
Brief commentary
O believers! If those who disbelieved in Allah and His Messenger were to fight you, they would turn their backs, defeated and fleeing. They would not find any guardian who would take care of their matter, nor any helper who would help them in fighting against you.
