Al Baqarah, 209 Ayah
2:209
فَإِن زَلَلۡتُم مِّنۢ بَعۡدِ مَا جَآءَتۡكُمُ ٱلۡبَيِّنَٰتُ فَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ عَزِيزٌ حَكِيمٌ ٢٠٩
Fa'in Zalaltum Min Ba`di Mā Jā'atkumu Al-Bayyinātu Fā`lamū 'Anna Al-Laha `Azīzun Ĥakīmun
But if you deviate after clear proofs have come to you, then know that Allah is Exalted in Might and Wise.
