Al-Israa 17:106

وَقُرْءَانًۭا فَرَقْنَٰهُ لِتَقْرَأَهُۥ عَلَى ٱلنَّاسِ عَلَىٰ مُكْثٍۢ وَنَزَّلْنَٰهُ تَنزِيلًۭا

Wa quraanan faraqnaahu litaqra ahoo 'alan naasi 'alaa muksinw wa nazzalnaahu tanzeelaa

We have revealed the Qur'an in parts that you may recite it to people slowly and with deliberation; and (for that reason) We have revealed it gradually (to suit particular occasions).
