Sahih Bukhari, Chapter: Oppressions (Al-Mazalim)

Allah's Apostle (SAW) said, "When the believers pass safely over (the bridge across) Hell, they will be stopped at a bridge in between Hell and Paradise where they will retaliate upon each other for the injustices done among them in the world, and when they get purified of all their sins, they will be admitted into Paradise. By Him in Whose Hands the life of Muhammad (SAW) is everybody will recognize his dwelling in Paradise better than he recognizes his dwelling in this world."
