18:27
وَٱتْلُ مَآ أُوحِىَ إِلَيْكَ مِن كِتَابِ رَبِّكَ ۖ لَا مُبَدِّلَ لِكَلِمَـٰتِهِۦ وَلَن تَجِدَ مِن دُونِهِۦ مُلْتَحَدًا
wa-ut'lu mā ūḥiya ilayka min kitābi rabbika lā mubaddila likalimātihi walan tajida min dūnihi mul'taḥadan
[Prophet], follow what has been revealed to you of your Lord’s Scripture: there is no changing His words, nor can you find any refuge except with Him.
And recite what has been revealed to you (O Muhammad صلى الله عليه وسلم) of the Book (the Qur’ân) of your Lord (i.e. recite it, understand and follow its teachings and act on its orders and preach it to men). None can change His Words, and none will you find as a refuge other than Him.
