quran:2:66 –

And We made it a deterrent punishment for those who were present and those who succeeded ˹them˺ and a lesson for those who fear Allah.  

And We made it, this punishment, an exemplary punishment, a lesson to dissuade others from doing what they did; for all the former times and for the latter, that is, for the people of that time or those that came later; and an admonition to such as who fear, God: these are singled out for mention here because they, in contrast to others, are the ones who benefit thereby.
القرآن:٢:٦٦ –

فَجَعَلْنَاهَا نَكَالًا لِمَا بَيْنَ يَدَيْهَا وَمَا خَلْفَهَا وَمَوْعِظَةً لِلْمُتَّقِينَ  

{فجعلناها} أي تلك العقوبة {نكالاً} عبرة مانعة من ارتكاب مثل ما عملوا {لما بين يديها وما خلفها} أي للأمم التي في زمانها وبعدها {وموعظة للمتقين} الله وخصوا بالذكر لأنهم المنتفعون بخلاف غيرهم.
