﴿ إِنَّهَا شَجَرَةٌۭ تَخْرُجُ فِىٓ أَصْلِ ٱلْجَحِيمِ ﴾

“for, behold, it is a tree that grows in the very heart of the blazing fire [of hell],”

Indeed it is a tree that comes forth from the very source of Hell in other words from the depths of Hell with its branches extending up through all its different levels.
