19th Ayah from Surah Al Buruj
But they who disbelieve are in [persistent] denial,
Yet still the disbelievers persist in denial.
Nay! The disbelievers (persisted) in denying (Prophet Muhammad (Peace be upon him) and his Message of Islamic Monotheism).
But those who disbelieve are (engaged) in denying (the truth).
Nay, but those who disbelieve live in denial
And yet the Unbelievers (persist) in rejecting (the Truth)!
