The Prophet ﷺ said, "Paradise and the Fire disputed before their Lord.Paradise said, 'My Lord, what is the matter with me that none enter me except the weak and lowly among people?'The Fire said, 'I have been favored with the arrogant.'Allah the Exalted said to Paradise, 'You are My mercy,' and He said to the Fire, 'You are My punishment, through which I afflict whomever I will. Each of you shall have her fill.'"He continued, "As for Paradise, Allah does not wrong any of His creation, so He creates new beings for the Fire as He wills, and they are cast into it. It will say, 'Is there any more?' three times, until He places His foot upon it. Then it becomes full, its parts folding into one another, and it says, 'Enough, enough, enough.'"
عن النبي ﷺ قال: اختصمت الجنة والنار إلى ربهما، فقالت الجنة: يا رب ما لها لا يدخلها إلا ضعفاء الناس وسقطهم، وقالت النار: -يعني- أوثرت بالمتكبرين، فقال الله تعالى للجنة: أنت رحمتي، وقال للنار: أنت عذابي أصيب بك من أشاء، ولكل واحدة منكما ملؤها. قال: فأما الجنة فإن الله لا يظلم من خلقه أحدا، وإنه ينشئ للنار من يشاء، فيلقون فيها فتقول: هل من مزيد ثلاثا، حتى يضع فيها قدمه، فتمتلئ ويرد بعضها إلى بعض، وتقول: قط قط قط.
Bukhari narrated it in Tawhid (7449), from Ubaydullah bin Saad bin Ibrahim, who said, my father Yaqub told us, who said, my father told us, from Salih bin Kaysan, from Araj, from Abu Hurairah, and he related it.Muslim also narrated it in Paradise and the Description of Its Bliss (2846), through another route, from Araj, in a similar manner.
