Surah Al-Fat'h (The Victory), Verse 22

وَلَوْ قَاتَلَكُمُ الَّذِیْنَ كَفَرُوْا لَوَلَّوُا الْاَدْبَارَ ثُمَّ لَا یَجِدُوْنَ وَلِیًّا وَّلَا نَصِیْرًا ۟

Wa law qaatalakumul lazeena kafaroo la wallawul adbaara summa laa yajidoona waliyanw-wa laa naseeraa

“If the Unbelievers should fight you, they would certainly turn their backs; then would they find neither protector nor helper.”
