We would say to Hell on the Day of Ressurection: 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 ﷺ 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 there- in 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 accommo- date that spare place in Paradise. (Using translation from Muslim 2848c)
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ لَا تَزَالُ جَهَنَّمُ يُلْقَى فِيهَا وَتَقُولُ هَلْ مِنْ مَزِيدٍ؟ حَتَّى يَضَعَ رَبُّ الْعِزَّةِ فِيهَا قَدَمَهُ فَيَنْزَوِيَ بَعْضُهَا إِلَى بَعْضٍ وَتَقُولُ قَطْ قَطْ وَعِزَّتِكَ وَكَرَمِكَ وَلَا يَزَالُ فِي الْجَنَّةِ فَضْلٌ حَتَّى يُنْشِئَ اللهُ لَهَا خَلْقًا فَيُسْكِنَهُمْ فَضْلَ الْجَنَّةِ
