Surah Az-Zumar (The Successive Groups), Verse 36

اَلَیْسَ اللّٰهُ بِكَافٍ عَبْدَهٗ وَیُخَوِّفُوْنَكَ بِالَّذِیْنَ مِنْ دُوْنِهٖ وَمَنْ یُّضْلِلِ اللّٰهُ فَمَا لَهٗ مِنْ هَادٍ ۟

Alaisal laahu bikaafin 'abdahoo wa yukhawwi foonaka billazeena min doonih; wa mai yudlilil laahu famaa lahoo min haad

“Is not Allah enough for his Servant? But they try to frighten thee with other (gods) besides Him! for such as Allah leaves to stray, there can be no guide.”
