quran:2:78 –

And among them are unlettered ones who do not know the Scripture except in wishful thinking, but they are only assuming.  

And there are some of them, the Jews, that are illiterate, unlettered, not knowing the Scripture, the Torah, but only desires, lies which were handed down to them by their leaders and which they relied upon; and, in their rejection of the prophethood of the Prophet and fabrications of other matters, they have, mere conjectures, and no firm knowledge.
القرآن:٢:٧٨ –

وَمِنْهُمْ أُمِّيُّونَ لَا يَعْلَمُونَ الْكِتَابَ إِلَّا أَمَانِيَّ وَإِنْ هُمْ إِلَّا يَظُنُّونَ  

{ومنهم} أي اليهود {أميون} عوام {لا يعلمون الكتاب} التوراة {إلا} لكن {أمانيَّ} أكاذيب تلقَّوْها من رؤسائهم فاعتمدوها {وإن} ما {هم} في جحد نبوة النبي وغيره مما يختلقونه {‌إلا يظنون} ظناً ولا علم لهم.
