And for drink you are served with molten intestines of fellow mujrimiin
And they will eat the tree of Zaqqum. If one drop of the tree of Zaqqum were to drop on earth, it would turn everyone's life upside down.
Verily the tree of Zaqqum will be the food of the Sinful like molten brass; it will boil in their insides. Like the boiling of scalding water. (A voice will cry "Seize ye him and drag him into the midst of the Blazing Fire! Then pour over his head the Penalty of Boiling Water; Taste thou (this)! Truly wast thou Mighty full of honour! Truly this is what you used to doubt.” (Surah ad-Dukhan 43-50)
The tree of Zaqqum mentioned in the verse is the tree that God Almighty created in Hell and named as "cursed tree". When the people of Hell get hungry, they go to this tree and eat from it. This tree boils like hot water in their abdomens. God Almighty makes the tree of Zaqqum boil like molten copper in their abdomens.
The Prophet (pbuh) sates the following about the tree of Zaqqum:
“If one drop from the tree of Zaqqum were to fall into the seas of the world, it would turn the life of everybody upside down. What about the state of those who will eat Zaqqum?” (Tirmidhi, Jahannam, 4; Hakim, al-Mustadrak, 2/294)
May Allah protect us from Hellfire and put us into Jannah.
