quran:37:67

Then indeed, they will have after it a mixture of scalding water.  

Then, lo!, on top of it they will have a brew of boiling water, which they drink and which mixes with what they have eaten and becomes a brew thereof.
القرآن:٣٧:٦٧

ثُمَّ إِنَّ لَهُمْ عَلَيْهَا لَشَوْبًا مِنْ حَمِيمٍ  

{ثم إن لهم عليها لشوبا من حميم} أي ماء حار يشربونه فيختلط بالمأكول منها فيصير شوبا له.
