Sahih al-Bukhari 97:14
Narrated Anas:
The Prophet (ﷺ) said, "(The people will be thrown into Hell ( Fire) and it will keep on saying, 'Is there any more?' till the Lord of the worlds puts His Foot over it, whereupon its different sides will come close to each other, and it will say, 'Qad! Qad! (enough! enough!) By Your 'Izzat (Honor and Power) and YOUR KARAM (Generosity)!' Paradise will remain spacious enough to accommodate more people until Allah will create some more people and let them dwell in the superfluous space of Paradise. "

حَدَّثَنَا ابْنُ أَبِي الأَسْوَدِ، حَدَّثَنَا حَرَمِيٌّ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " يُلْقَى فِي النَّارِ ". وَقَالَ لِي خَلِيفَةُ حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ حَدَّثَنَا سَعِيدٌ عَنْ قَتَادَةَ عَنْ أَنَسٍ. وَعَنْ مُعْتَمِرٍ سَمِعْتُ أَبِي عَنْ قَتَادَةَ عَنْ أَنَسٍ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ يَزَالُ يُلْقَى فِيهَا وَتَقُولُ هَلْ مِنْ مَزِيدٍ. حَتَّى يَضَعَ فِيهَا رَبُّ الْعَالَمِينَ قَدَمَهُ فَيَنْزَوِي بَعْضُهَا إِلَى بَعْضٍ، ثُمَّ تَقُولُ قَدْ قَدْ بِعِزَّتِكَ وَكَرَمِكَ. وَلاَ تَزَالُ الْجَنَّةُ تَفْضُلُ حَتَّى يُنْشِئَ اللَّهُ لَهَا خَلْقًا فَيُسْكِنَهُمْ فَضْلَ الْجَنَّةِ ".
