Surah Az-Zukhruf 43:88

وَقِيلِهِۦ يَـٰرَبِّ إِنَّ هَـٰٓؤُلَآءِ قَوْمٌ لَّا يُؤْمِنُونَ

And [Allāh acknowledges] his saying, "O my Lord, indeed these are a people who do not believe."

Translation: Saheeh International

Tafsir

And as for his saying that is the saying of the Prophet Muhammad (s) wa-qīlihi is accusative dependent because it is a verbal noun followed by an implicit verb in other words wa-qāla qīlihi ‘and he said his saying’ ‘O my Lord! These are indeed a people who have no faith’.
