وَاذْكُرْ أَخَا عَادٍ إِذْ أَنذَرَ قَوْمَهُ بِالْأَحْقَافِ وَقَدْ خَلَتِ النُّذُرُ مِن بَيْنِ يَدَيْهِ وَمِنْ خَلْفِهِ أَلَّا تَعْبُدُوا إِلَّا اللَّهَ إِنِّي أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ عَظِيمٍ

AND REMEMBER that brother of [the tribe of] Ad, how - seeing that [other] warnings had already come and gone within his own knowledge as well as in times beyond his ken - he warned his people [who lived] among those sand-dunes: Worship none but God! Verily, I fear lest suffering befall you on an awesome day!"

And mention the brother of 'Ad; when he warned his people in the sandy plains -- and warners indeed came before him and after him -- saying: Serve none but Allah. Surely I fear for you the chastisement of a grievous day.

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