But if you do (it) not and never shall you do (it), then be on your guard against the fire of which men and stones are the fuel; it is prepared for the unbelievers.

Pickthall
And if ye do it not - and ye can never do it - then guard yourselves against the Fire prepared for disbelievers, whose fuel is of men and stones.
