And indeed, it will be [a cause of] regret upon the disbelievers.
this will be a source of bitter regret for the disbelievers-
And indeed it (this Quran) will be an anguish for the disbelievers (on the Day of Resurrection).
And surely, it is a cause of remorse for the disbelievers.
And lo! it is indeed an anguish for the disbelievers.
But truly (Revelation) is a cause of sorrow for the Unbelievers.
