Al-An'am 6:115

وَتَمَّتْ كَلِمَتُ رَبِّكَ صِدْقًا وَعَدْلًا ۚ لَّا مُبَدِّلَ لِكَلِمَـٰتِهِۦ ۚ وَهُوَ ٱلسَّمِيعُ ٱلْعَلِيمُ

Watammat kalimatu rabbika ṣid'qan waʿadlan lā mubaddila likalimātihi wahuwa l-samīʿu l-ʿalīmu

And the word of your Lord has been fulfilled in truth and in justice. None can alter His words, and He is the Hearing, the Knowing.
