Qur'an 18:27 · Al-Kahf

وَٱتْلُ مَآ أُوحِىَ إِلَيْكَ مِن كِتَابِ رَبِّكَ ۖ لَا مُبَدِّلَ لِكَلِمَٰتِهِۦ وَلَن تَجِدَ مِن دُونِهِۦ مُلْتَحَدًۭا

(27) And recite, [O Muḥammad], what has been revealed to you of the Book of your Lord. There is no changer of His words, and never will you find in other than Him a refuge.
