Al-Mulk 67:20

Amman hatha allathee huwajundun lakum yansurukum min dooni arrahmaniini alkafiroona illa fee ghuroor

Or who is it that could be an army for you to aid you other than the Most Merciful? The disbelievers are not but in delusion.

Now, who is there to act as a force for you to help you, except the RaHmān ? The disbelievers are in nothing but delusion.
