Qur'ān 9:115 · At-Tawbah (التوبة)
وَمَا كَانَ ٱللَّهُ لِيُضِلَّ قَوْمًۢا بَعْدَ إِذْ هَدَىٰهُمْ حَتَّىٰ يُبَيِّنَ لَهُم مَّا يَتَّقُونَ ۚ إِنَّ ٱللَّهَ بِكُلِّ شَىْءٍ عَلِيمٌ
And Allah would not let a people stray after He has guided them until He makes clear to them what they should avoid. Indeed, Allah is Knowing of all things.
