The Messenger of Allah (Sallallaahu `alayhi wa sallam) said,

“Paradise and Hell-fire disputed together, and Hell-fire said: ‘In me are the mighty and the haughty.’ Paradise said: ‘In me are the weak and the poor.’ So Allah judged between them, [saying]: ‘You are Paradise, My mercy; through you I show mercy to those I wish. And you are Hell-fire, My punishment; through you I punish those I wish, and it is incumbent upon Me that each of you shall have its fill.’”
