﴿ 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 thy Lord) the Qur'an, detailing the commands and prohibitions (in truth) in His speech (and justice) from Him. (There is naught that can change His words) the Qur'an; it is also said that this means: the Word of your Lord has prescribed that His friends shall triumph. He is truthful in His speech and just in that which shall come. Nothing can change His words about His giving help to His friend. It is also said that this means: the religion of your Lord is now manifest, people truthfully believe that it is Allah's religion. Allah's command is just and nothing will ever change His religion. (He is the Hearer) of their speech, (the Knower) of them and their works.
