At-Tawbah 115

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

wamā kāna l-lahu liyuḍilla qawman baʿda idh hadāhum ḥattā yubayyina lahum mā yattaqūna inna l-laha bikulli shayin ʿalīmun

And Allāh would not let a people stray after He has guided them until He makes clear to them what they should avoid. Indeed, Allāh is Knowing of all things.
