Al-Ahqaf 46:21

Wathkur akha AAadinith anthara qawmahu bil-ahqafiwaqad khalati annuthuru min bayni yadayhi waminkhalfihi alla taAAbudoo illa Allaha inneeakhafu AAalaykum AAathaba yawmin AAatheem

And mention, [O Muḥammad], the brother of ʿAad, when he warned his people in [the region of] al-Aḥqāf - and warners had already passed on before him and after him - [saying], "Do not worship except Allāh. Indeed, I fear for you the punishment of a terrible day."

And recall the brother of (the nation of) ‘Ād, when he warned his people at the long, curved sand dunes- while many warners have passed before him and after him (with the same message)-saying, “Do not worship anyone except Allah. Surely I fear for you the punishment of a terrible day.”
