6:105
وَكَذَٰلِكَ نُصَرِّفُ ٱلْـَٔايَـٰتِ وَلِيَقُولُوا۟ دَرَسْتَ وَلِنُبَيِّنَهُۥ لِقَوْمٍ يَعْلَمُونَ
wakadhālika nuṣarrifu l-āyāti waliyaqūlū darasta walinubayyinahu liqawmin yaʿlamūna
This is how We explain Our revelations in various ways- though they will say, ‘You [Muhammad] have been studying’- to make them clear for those who know.
Thus We explain variously the Verses so that they (the disbelievers) may say: "You have studied (the Books of the people of the Scripture and brought this Qur’ân from that)" and that We may make the matter clear for the people who have knowledge.
