﴿ وَتَمَّتْ كَلِمَتُ رَبِّكَ صِدْقًۭا وَعَدْلًۭا ۚ لَّا مُبَدِّلَ لِكَلِمَٰتِهِۦ ۚ وَهُوَ ٱلسَّمِيعُ ٱلْعَلِيمُ ﴾

“for, truly and justly has thy Sustainer's promise been fulfilled. There is no power that could alter [the fulfilment of] His promises: and He alone is all-hearing, all-knowing.”

Perfected is the word of your Lord in the way of rulings and appointed terms in truthfulness and justice sidqan wa-‘adlan is for specification; none can change His words either by contravening His rulings or evading His appointed terms. He is the Hearing of what is said the Knowing of what is done.
