Abu Huraira reported:We were in the company of Allah's Messenger (ﷺ) that we heard a terrible sound. Thereupon Allah's Apostle (ﷺ) said: Do you know what (sound) is this? We said: Allah and His Messenger know best. Thereupon he said: That is a stone which was thrown seventy years before in Hell and it has'been constantly slipping down and now it has reached its base.
حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، حَدَّثَنَا خَلَفُ بْنُ خَلِيفَةَ، حَدَّثَنَا يَزِيدُ بْنُ كَيْسَانَ، عَنْ أَبِي، حَازِمٍ عَنْ أَبِي هُرَيْرَةَ، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم إِذْ سَمِعَ وَجْبَةً فَقَالَ النَّبِيُّ صلى الله عليه وسلم " تَدْرُونَ مَا هَذَا " . قَالَ قُلْنَا اللَّهُ وَرَسُولُهُ أَعْلَمُ . قَالَ " هَذَا حَجَرٌ رُمِيَ بِهِ فِي النَّارِ مُنْذُ سَبْعِينَ خَرِيفًا فَهُوَ يَهْوِي فِي النَّارِ الآنَ حَتَّى انْتَهَى إِلَى قَعْرِهَا " .
