زفر
 
Appears 3 times in the Quran.
- 
    
So as to those who are unhappy, they shall be in the fire; for them shall be sighing and groaning in it: 
 
- 
    
For them therein shall be groaning and therein they shall not hear. 
 
- 
    
When it shall come into their sight from a distant place, they shall hear its vehement raging and roaring.
