The Sandhills/46:26
We placed them in places where We did not place you. We gave them the senses of hearing and sight and brains. But neither their hearing nor their sight nor their brains were of any use to them, because they deliberately disbelieved in the signs of Allah. And that which they mocked at surrounded them.
