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

“And God would never-after having invited them to His guidance -condemn people for going astray ere He has made [entirely] clear unto them of what they should beware. Verily, God has full knowledge of everything.”

(It was never Allah's (part) that he should send a folk astray) that he should leave a folk in error; it is also said this means: Allah will never thwart the works of a folk (after He had guided them) to faith (until He had made clear unto them what they should avoid) that which has been abrogated by means of that which has abrogated it. (Lo! Allah is Aware of all things) the abrogated and the abrogating.
