And indeed it will be a [matter of] regret for the faithless.

And indeed it is a despair for the disbelievers.

Surely it is a sorrow to the unbelievers;

And indeed, it (is) surely a regret upon the disbelievers.

And verily it shall be an occasion of anguish Unto the infidels.

And indeed it (this Quran) will be an anguish for the disbelievers (on the Day of Resurrection).

and surely it will be a cause of regret for the unbelievers.

and (on the Day of Judgment) this will be a great source of regret for the unbelievers.

And most surely it is a great grief to the unbelievers.

And lo! it is indeed an anguish for the disbelievers.

Indeed, it is a sorrow to the unbelievers

And indeed, it will be [a cause of] regret upon the disbelievers.

And it is surely a source of grief for the unbelievers.

it will be a source of bitter regret for those who deny the truth --

But truly (Revelation) is a cause of sorrow for the Unbelievers.
