(Al-Inshiqaaq ) 84 : 24
فَبَشِّرْهُمْ بِعَذَابٍ أَلِيمٍ
Then give them the glad tidings of a painful punishment.
For the disbelievers who hide and reject Adhikr, there is a painful punishment in the Hellfire. They are the fuel of Hellfire from mankind. See explanation 4: 137–138; 31: 5–7; and 64: 10.
