quran:17:77 –

˹That is Our˺ established way for those We had sent before you of Our messengers; and you will not find in Our way any alteration.  

˹That is˺ the way in the case of those whom We have sent from among Our messengers before you, that is to say, ˹that is˺ Our way ˹of dealing˺ with them ˹their enemies˺, destroying those who expel them ˹Our messengers˺. And as regards Our ˹established˺ way you will not find any change, any alternative ˹manner˺.
القرآن:١٧:٧٧ –

سُنَّةَ مَنْ قَدْ أَرْسَلْنَا قَبْلَكَ مِنْ رُسُلِنَا ۖ وَلَا تَجِدُ لِسُنَّتِنَا تَحْوِيلًا  

{سنّة من قد أرسلنا قبلك من رسلنا} أي كسنتنا فيهم من إهلاك من أخرجهم {ولا تجد لسنتنا تحويلاً} تبديلاً.
