Verse 115

وَمَا كَانَ ٱللَّهُ لِيُضِلَّ قَوْمًۢا بَعْدَ إِذْ هَدَىٰهُمْ حَتَّىٰ يُبَيِّنَ لَهُم مَّا يَتَّقُونَ إِنَّ ٱللَّهَ بِكُلِّ شَىْءٍ عَلِيمٌ

And God never misleads a people after He has guided them unless it is proven that they are no longer righteous. Indeed God is knowledgeable of all things.
