Surah Al-Ahqaf
قُلْ أَرَءَيْتُمْ إِن كَانَ مِنْ عِندِ ٱللَّهِ وَكَفَرْتُم بِهِۦ وَشَهِدَ شَاهِدٌ مِّنۢ بَنِىٓ إِسْرَٰٓءِيلَ عَلَىٰ مِثْلِهِۦ فَـَٔامَنَ وَٱسْتَكْبَرْتُمْ ۖ إِنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّـٰلِمِينَ
Qul ara'aitum in kāna min ‘indillāhi wa kafartum bihī wa syahida syāhidum mim banī isrā'īla ‘alā miṡlihī fa āmana wastakbartum, innallāha lā yahdil-qaumaẓ-ẓālimīn(a).
Say, "Have you considered: if the Qur'an was from Allah, and you disbelieved in it while a witness from the Children of Israel has testified to something similar and believed while you were arrogant...?" Indeed, Allah does not guide the wrongdoing people.
