فصّلت — Fussilat Ayat 52

قُلْ اَرَءَيْتُمْ اِنْ كَانَ مِنْ عِنْدِ اللّٰهِ ثُمَّ كَفَرْتُمْ بِهٖ مَنْ اَضَلُّ مِمَّنْ هُوَ فِيْ شِقَاقٍۢ بَعِيْدٍ

Qul ara'aitum in kāna min ‘indillāhi ṡumma kafartum bihī man aḍallu mimman huwa fī syiqāqim ba‘īd(in).

"Say, "Have you considered: if the Qur'an is from Allah and you disbelieved in it, who would be more astray than one who is in extreme dissension?""
