“Paradise and the Fire quarreled. Paradise said, ‘The weak and the poor enter me.’ The Fire replied, ‘The oppressive and the proud enter me.’ So Allah Almighty said to the Fire, ‘You are my punishment, in you I punish whom I wish.’ He said to Paradise, ‘You are my mercy to whom I wish, and each of you will certainly be filled.'” [Muslim, at-Tirmidhi, Ibn Khuzaimah]
