وَاتْلُ مَا أُوحِيَ إِلَيْكَ مِن كِتَابِ رَبِّكَ لَا مُبَدِّلَ لِكَلِمَاتِهِ وَلَن تَجِدَ مِن دُونِهِ مُلْتَحَدًا
Recite what has been revealed to you from the Book of your Lord. Nothing can change His words, and you will never find any refuge besides Him.
Agha Ali Puya Commentary
Commentary on Quran 18:27
[Pooya/Ali Commentary 18:27] The Holy Prophet is commanded to recite the verses, that have been revealed to him, from the book of his Lord, in reply to the query about the ashab ul kahf the Quraysh put to him as directed by the Jews. The people are warned through the Holy Prophet not to try to change the words of Allah because His commands, decrees and orders are final and irrevocable. See commentary of An-am: 116.
