I looked hard and can't find the exact verse, but there's a specific verse in the Quran that basically says the same thing:

If all of humanity gathered to believe, it wouldn't add Him anything. And if all of humanity gathered to disbelieve, it wouldn't remove anything from Him.

People still have this latent idea of God as an old bearded guy (or any variation of that myth) "interacting" with the world (via spells and miracles).
