Then by (the) Lord (of) the heaven and the earth, indeed, it (is) surely (the) truth (just) as [what] you speak.

Translations:

for, by the Sustainer of heaven and earth, this [life after death] is the very truth - as true as that you are endowed with speech!

Then, by the Lord of heaven and earth, this is the very Truth, as much as the fact that ye can speak intelligently to each other.

And by the Lord of the heavens and the earth, it is the truth, even as (it is true) that ye speak.

So by the Lord of the heavens and the earth! it is surely the truth, just as you speak.

Then by the Lord of the heaven and earth, indeed, it is truth - just as [sure as] it is that you are speaking.
