Sura al-Mulk 67:20

أَمَّنْ هَٰذَا ٱلَّذِى هُوَ جُندٌ لَّكُمْ يَنصُرُكُم مِّن دُونِ ٱلرَّحْمَٰنِ إِنِ ٱلْكَٰفِرُونَ إِلَّا فِى غُرُورٍ

a-man hādhā alladhī huwa jundun la-kum yanṣurukum min dūni l-raḥmāni ini l-kāfirūna illā fī ghurūrin

Nay, who is there that can help you, (even as) an army, besides (Allah) Most Merciful? In nothing but delusion are the Unbelievers.
