The Grave its Torment and its Pleasure

It is related that Abu Hurairah said: "We were walking with the Messenger of Allah (sallallahu alaihi wa sallam) when we passed two graves. Then he stood still and we stood with him. His color started to change and he rolled up his sleeves, so we said: 'What's the matter, oh Prophet of Allah ?', he said: 'Don't you hear what I'm hearing?' We said: 'What is it, oh Prophet of Allah?' He said: 'These two men are being severely punished in their graves for a relatively minor sin." We said: 'For what are they punished, oh Prophet of Allah?' He said: 'One of them never used to clean urine from himself, and the other used to harm the people by his speech and walk among the people carrying tales.'
