[Machine] From the Prophet ﷺ , he said, "If seven layers of fat from their bodies were taken and thrown from the edge of Hellfire, they would not reach its end even after seventy years." This hadith has a valid chain of narrators.
عَنِ النَّبِيِّ ﷺ قَالَ «لَوْ أُخِذَ سَبْعُ خَلِفَاتٍ بِشُحُومِهِنَّ فَيُلْقَيْنَ مِنْ شَفِيرِ جَهَنَّمَ مَا انْتَهَيْنَ إِلَى آخِرِهَا سَبْعِينَ عَامًا» سنده صالح
