Az-Zukhruf - 43:88

وَقِيلِهِ يَارَبِّ إِنَّ هَؤُلَاء قَوْمٌ لَّا يُؤْمِنُونَ
[43:88]
Consider his cry: O my Lord! surely they are a people who do not believe.
(Allah has knowledge) of the (Prophet's) cry, "O my Lord! Truly these are people who will not believe!"
And he saith: O my Lord! Lo! these are a folk who believe not.
