Surah Al-Baqarah, Verse 78

وَمِنۡهُمۡ أُمِّيُّونَ لَا يَعۡلَمُونَ ٱلۡكِتَٰبَ إِلَّآ أَمَانِيَّ وَإِنۡ هُمۡ إِلَّا يَظُنُّونَ٧٨

wamin'hum ummiyyūna lā yaʿlamūna l-kitāba illā amāniyya wa-in hum illā yaẓunnūna

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