quran:43:88 –

And ˹Allah acknowledges˺ his saying, "O my Lord, indeed these are a people who do not believe."  

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’.
