Abu Hurairah (RA) reported that Allah’s Messeger (SAW) said:"Paradise and Hell debated with one another. Paradise said, ‘The weak and the poor will enter me." Hell boasted, “The tyrants and the arrogant will come to me.” (Allah) said to Hell, “You are My punishment. I take revenge from whom I like through You.” And to Paradise, He said, ‘You are My mercy. Through you, I show mercy to whomsoever I like.”
[Bukhari 4850, Muslim 2846]
