Chapter 54: The Book of Paradise, its Description, its Bounties and its Inhabitants
Samura b. Jundub reported Allah' s Messenger (ﷺ) as saying: 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.
