Sahih Adab al-Mufrad

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) that he said: "Paradise and Hell argued with each other," and Sufyan also said: "Paradise and Hell quarreled. Hell said: 'The oppressors (and tyrants) will be gathered in me, and the arrogant will enter me.' And Paradise said: 'The weak will enter me, and the poor will enter me.' Allah, Blessed and Exalted, said to Paradise: 'You are My mercy; I will show mercy through you to whom I wish.' And He said to Hell: 'You are My punishment; I will punish through you whom I wish. And I will fill both of you.'"
