There would be among them those to whom the fire will reach up to their ankels and to some of them the fire would reach their knees and to some it would reach their waists and to some it would reach up to their collar-bones. (Using translation from Muslim 2845b)
عَنِ النَّبِيِّ ﷺ قَالَ مِنْهُمْ مَنْ تَأْخُذُهُ النَّارُ إِلَى رُكْبَتَيْهِ وَمِنْهُمْ مَنْ تَأْخُذُهُ النَّارُ إِلَى حُجْزَتِهِ وَمِنْهُمْ مَنْ تَأْخُذُهُ إِلَى تَرْقُوَتِهِ
