Whenever they try to escape from anguish, they are dragged back and told, “Taste the torment of burning.”
22:22Whenever, in their anguish, they would go forth from thence they are driven back therein and (it is said unto them): Taste the doom of burning.
32:20And as for those who do evil, their retreat is the Fire. Whenever they desire to issue forth from thence, they are brought back thither. Unto them it is said: Taste the torment of the Fire which ye used to deny.
