say have you considered if the quran 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.
قل أرأيتم إن كان من عند الله وكفرتم به وشهد شاهد من بني إسرائيل على مثله فآمن واستكبرتم إن الله لا يهدي القوم الظالمين
