But nay - the Last Hour is the time when they shall truly meet their fate; and that Last Hour will be most calamitous, and most bitter:

Nay, the Hour (of Judgment) is the time promised them (for their full recompense): And that Hour will be most grievous and most bitter.

Nay, but the Hour (of doom) is their appointed tryst, and the Hour will be more wretched and more bitter (than their earthly failure).

Are your disbelievers better than these, or have you an immunity in the scriptures?

But the Hour is their appointment [for due punishment], and the Hour is more disastrous and more bitter.
