سورة الواقعة (Al-Waqi'ah) - The Event

وَإِذَا رُدُّوا إِلَىٰ جَهَنَّمَ قِيلَ هَٰذَا مَا كُنتُمْ تُكَذِّبُونَ

And when they are returned to Hell, it will be said, "This is what you used to deny."

This verse highlights the irony faced by those who disbelieved in the Day of Judgment. They will be confronted with the reality of their eternal punishment in Hell, a stark contrast to their previous denial.

وَإِنَّ لَكُمْ عَلَيْهَا لَزُمًا

And indeed, there is a fixed term for you upon it.

This verse emphasizes the inevitability of the punishment in Hell. It serves as a warning that the torment will not be temporary but will endure for a predetermined period.
