Sahih Muslim Book 40, Hadith Number 6825.
‘Abd al-Wahhab b. Ata’ reported in connection with the words of Allah, the Exalted and the Glorious: We would say to Hell on the Day of Resurrection: Have you been completely filled up? and it would say: Is there anything -more? And he stated on the authority of Anas b. Malik that Allah’s Apostle (may peace be upon him) said: (The sinners) would be thrown therein and it would continue to say: Is there anything more, until Allah, the Exalted and Glorious, would keep His foot therein and some of its part would draw close to the other and it would say: Enough, enough, by Thy Honour and by Thy Dignity, and there would be enough space in Paradise until Allah would create a new creation and He would make them accommodate that spare place in Paradise.
