The Holy Quran 18:27 — Surah Al-Kahf
Arabic text
وَٱتْلُ مَآ أُوحِىَ إِلَيْكَ مِن كِتَابِ رَبِّكَ ۖ لَا مُبَدِّلَ لِكَلِمَـٰتِهِۦ وَلَن تَجِدَ مِن دُونِهِۦ مُلْتَحَدًا
Translation
Recite (to people) what (revelation) has been revealed to you from the Book of your Rabb (the Qur'aan). There is none who can alter His words (Allaah's words in the Qur'aan and His promises) and (if you dare try to alter His words,) you will certainly not find another place of refuge (a shelter to save you from His punishment) besides with Him (only He can save you from anything).
Tafsir (excerpt) — Tafsir Usmani
The command to the Prophet ﷺ to recite the revelation: earlier, concerning the story of the People of the Cave, it was said: فَلَا تُمَارِ فِيْهِمْ اِلَّا مِرَآءً ظَاهِرًا وَّلَا تَسْتَفْتِ فِيْهِمْ مِّنْهُمْ اَحَدًا (“So do not argue about them except in a passing discussion, and do not ask any of them about them”).
