Al-An'am 6:105

وَكَذَٰلِكَ نُصَرِّفُ ٱلْـَٔايَـٰتِ وَلِيَقُولُوا۟ دَرَسْتَ وَلِنُبَيِّنَهُۥ لِقَوْمٍ يَعْلَمُونَ

Wakadhālika nuṣarrifu l-āyāti waliyaqūlū darasta walinubayyinahu liqawmin yaʿlamūna

And thus do We diversify the verses so they [i.e., the disbelievers] will say, "You have studied," and so We may make it [i.e., the Qur’ān] clear for a people who know.
