﴿ لَقَدْ حَقَّ ٱلْقَوْلُ عَلَىٰٓ أَكْثَرِهِمْ فَهُمْ لَا يُؤْمِنُونَ ﴾

“Indeed, the word [of God’s condemnation] is bound to come true against most of them: for they will not believe.”

The word for chastisement has already proved true it has become due for most of them for they in other words most of them will not believe.
