فَإِن زَلَلۡتُم مِّنۢ بَعۡدِ مَا جَآءَتۡكُمُ ٱلۡبَيِّنَٰتُ فَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ عَزِيزٌ حَكِيمٌ ٢٠٩

But if you slip [i.e., deviate] after clear proofs have come to you, then know that Allāh is Exalted in Might and Wise.

If you slip up or go astray after clear proofs have come to you, then know that Allah is Mighty in His ability and power, Wise in His planning and establishing of sacred laws. So, fear and glorify Him.
