Ahmed Raza Khan: Mohammed Aqib Qadri:
Flames of smokeless fire and black smoke
without flames, will be let loose on you, so you will not be able to retaliate.
Yusuf Ali:
On you will be sent (O ye evil ones twain!) a flame of fire (to burn) and a smoke (to choke): no defence will ye have:
Pickthal:
There will be sent, against you both, heat of fire and flash of brass, and ye will not escape.
