وَلَا تَكُوْنُوْا كَالَّذِیْنَ نَسُوا اللّٰهَ فَاَنْسٰىهُمْ اَنْفُسَهُمْ ؕ اُولٰٓىِٕكَ هُمُ الْفٰسِقُوْنَ ۟

Saheeh International
And be not like those who forgot Allāh, so He made them forget themselves. Those are the defiantly disobedient.
Al-Mukhtasar fi Tafsir
Do not become like those who forgot Allah by not fulfilling His commands nor refraining from the things He did not allow, so Allah made them forget themselves and they did not act upon that which would save them from the wrath and punishment of Allah. Those who forgot Allah and did not fulfil His commands or refrain from the things He did not allow are the ones who left the obedience of Allah.
