Ibrahim 14:18

Mathalu allatheena kafaroo birabbihimaAAmaluhum karamadin ishtaddat bihi arreehufee yawmin AAasifin la yaqdiroona mimmakasaboo AAala shay-in thalika huwa addalalualbaAAeed

The example of those who disbelieve in their Lord is [that] their deeds are like ashes which the wind blows forcefully on a stormy day; they are unable [to keep] from what they earned a [single] thing. That is what is extreme error.

The deeds of those who refuse to believe in their Lord are like ashes blown away by the wind on a stormy day. They will not be able to gain anything out of what they did. That is the farthest point of straying away from the right path.
