The Messenger of Allah ﷺ said, "Paradise and Hell disputed with one another.Hell said, 'I have been favored with the arrogant and the tyrannical.'Paradise said, 'What is the matter with me that none enter me except the weak among people, the lowly, and the hungry?'Allah said to Paradise, 'You are My mercy, through you I show mercy to whomever I will of My servants.'And He said to Hell, 'You are My punishment, through you I punish whomever I will of My servants. Each of you shall have its fill.'As for Hell, it will not be filled until Allah places His foot upon it, at which point it will say, 'Enough, enough, enough.' Then it will be filled, and its parts will be drawn together, and Allah does not wrong any of His creation. As for Paradise, Allah will create new beings to fill it."
قال رسول الله ﷺ: تحاجت الجنة والنار، فقالت النار: أوثرت بالمتكبرين والمتجبرين، وقالت الجنة: فما لي لا يدخلني إلا ضعفاء الناس وسقطهم وغرثهم؟ قال الله للجنة: إنما أنت رحمتي أرحم بك من أشاء من عبادي، وقال للنار: إنما أنت عذابي أعذب بك من أشاء من عبادي، ولكل واحدة منكما ملؤها، فأما النار فلا تمتلئ حتى يضع الله تبارك وتعالى رجله، تقول: قط قط قط، فهنالك تمتلئ، ويزوى بعضها إلى بعض، ولا يظلم الله من خلقه أحدا، وأما الجنة فإن الله ينشئ لها خلقا.
Bukhari narrated it in the tafsir (4850), and Muslim in the Book of Paradise (36/2846), both from Muhammad bin Rafi, who said, Abdul-Razzaq narrated to us, who said, Mamar informed us, from Hammam, from Abu Hurairah, who mentioned it.
