Surah Ghafir — Ayah 6 (40:6)
وَكَذَٰلِكَ حَقَّتۡ كَلِمَتُ رَبِّكَ عَلَى ٱلَّذِينَ كَفَرُوٓاْ أَنَّهُمۡ أَصۡحَٰبُ ٱلنَّارِ ٦
English translation (Saheeh International)
And thus has the word [i.e., decree] of your Lord come into effect upon those who disbelieved that they are companions of the Fire.
Brief commentary
Like how Allah decided to destroy those denying nations, the Word of your Lord, O Messenger, is binding against the disbelievers, that they will be the inmates of the Fire.
