At Tawbah, 115 Ayah
9:115
وَمَا كَانَ ٱللَّهُ لِيُضِلَّ قَوۡمَۢا بَعۡدَ إِذۡ هَدَىٰهُمۡ حَتَّىٰ يُبَيِّنَ لَهُم مَّا يَتَّقُونَۚ إِنَّ ٱللَّهَ بِكُلِّ شَيۡءٍ عَلِيمٌ ١١٥
Wa Mā Kāna Al-Lahu Liyuđilla Qawmāan Ba`da 'Idh Hadāhum Ĥattá Yubayyina Lahum Mā Yattaqūna ۚ 'Inna Al-Laha Bikulli Shay'in `Alīmun
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.
