باب الْحَلِفِ بِعِزَّةِ اللَّهِ وَصِفَاتِهِ وَكَلِمَاتِهِ
Sahih al-Bukhari 6661

Narrated Anas bin Malik:

The Prophet (ﷺ) said, "The Hell Fire will keep on saying: 'Are there anymore (people to come)?' Till the Lord of Power and Honor will put His Foot over it and then it will say, 'Qat! Qat! (sufficient! sufficient!) by Your Power and Honor. And its various sides will come close to each other (i.e., it will contract). "

حَدَّثَنَا آدَمُ، حَدَّثَنَا شَيْبَانُ، حَدَّثَنَا قَتَادَةُ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ لاَ تَزَالُ جَهَنَّمُ تَقُولُ هَلْ مِنْ مَزِيدٍ حَتَّى يَضَعَ رَبُّ الْعِزَّةِ فِيهَا قَدَمَهُ فَتَقُولُ قَطْ قَطْ وَعِزَّتِكَ‏.‏ وَيُزْوَى بَعْضُهَا إِلَى بَعْضٍ ‏"‏‏.‏ رَوَاهُ شُعْبَةُ عَنْ قَتَادَةَ‏.‏
