TABARANI 17559:
from Baʿḍ Ahl al-ʿIlm —
[Machine] The Messenger of Allah ﷺ said, "By the One in whose hand is my soul, after the space between the edge of the fire and its depths, there is a stone the weight of seven camel humps. It is made of their fats, meats, and offspring. A person will fall into it between the edges of the fire until they reach its depths for seventy autumns."
الطبراني ١٧٥٥٩:
عن بعض اهل العلم —
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «وَالَّذِي نَفْسِي بِيَدِهِ إِنَّ بَعْدَ مَا بَيْنَ شَفِيرِ النَّارِ إِلَى قَعْرِهَا لَصَخْرةً زِنَةُ سَبْعِ خَلِفَاتٍ بِشُحُومِهِنَّ ولُحُومِهِنَّ وَأَوْلَادِهِنَّ يَهْوِي فِيهَا بَيْنَ شَفِيرِ النَّارِ إِلَى أَنْ يَبْلُغَ قَعْرَهَا سَبْعِينَ خَرِيفًا»
