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

“AND CONVEY [to the world] whatever has been revealed to thee of thy Sustainer's writ. There is nothing that could alter His words; and thou canst find no refuge other than with Him.”
