A. Yusuf Ali:Translation:
Say, "The truth is from your Lord": Let him who will
believe, and let him who will, reject (it): 2371 for the
wrong-doers We have prepared a Fire whose (smoke
and flames), like the walls and roof of a tent, will hem
them in: if they implore relief they will be granted
water like melted brass, that will scald their faces,
how dreadful the drink! How uncomfortable a couch to
recline on!

Muhammad Asad:Translation:
And say: "The truth [has now come] from your Sustainer: let, then, him who wills, believe in it, and let him who wills, reject it." Verily, for all who sin against themselves [by rejecting Our truth] 39 We have readied a fire whose billowing folds will encompass them from all sides; 40 and if they beg for water, they will be given water [hot] like molten lead, which will scald their faces: how dreadful a drink, and how evil a place to rest!
2371 Our choice in our limited Free will involves a corresponding personal responsibility. We are offered the Truth: again and again it is pressed on ovir attention. If we reject it, we must take all the terrible consequences which are prefigured in the Fire of Hell. Its flames and roof will completely enclose us like a tent. Ordinarily there is water to quench the heat of thirst: here the only drink will be like molten brass, thick, heavy, burning, sizzling. Before it reaches the mouth of the unfortunates, drops of it will scald their faces as it is poured out.
