Fussilat 41:13

<h2>A Warning to the Disbelievers and a Reminder of the Story of `Ad and Thamud</h2><p>Allah says: `Say, O Muhammad, to these idolators who disbelieve in the message of truth that you have brought: If you turn away from that which I have brought to you from Allah, then I warn you of the punishment of Allah like the punishment that the past nations suffered for disbelieving in the Messengers.'</p><div class="arabic uthmani">صَـعِقَةً مِّثْلَ صَـعِقَةِ عَادٍ وَثَمُودَ</div><p>(a Sa`iqah like the Sa`iqah which overtook `Ad and Thamud.) and other similar nations who did what they did,</p><div class="arabic uthmani">إِذْ جَآءَتْهُمُ الرُّسُلُ مِن بَيْنِ أَيْدِيهِمْ وَمِنْ خَلْفِهِمْ</div><p>(When the Messengers came to them, from before them and behind them) This is like the Ayah:</p><div class="arabic uthmani">وَاذْكُرْ أَخَا عَادٍ إِذْ أَنذَرَ قَوْمَهُ بِالاٌّحْقَافِ وَقَدْ خَلَتِ النُّذُرُ مِن بَيْنِ يَدَيْهِ وَمِنْ خَلْفِهِ</div><p>(And remember (Hud) the brother of `Ad, when he warned his people in Al-Ahqaf. And surely, there have passed away warners before him and after him) (46:21). which means that in the neighboring towns and cities, Allah sent Messengers who commanded the people to worship Allah Alone with no partner or associate, and they brought good news as well as warnings. They saw the punishment Allah sent …

But if they turn away, then say: I warn you of a thunderbolt like the thunderbolt (which fell of old upon the tribes) of A'ad and Thamud;

But if they turn away, say thou: "I have warned you of a stunning Punishment (as of thunder and lightning) like that which (overtook) the 'Ad and the Thamud!"

But if they turn away, then say (O Muhammad SAW): "I have warned you of a Sa'iqah (a destructive awful cry, torment, hit, a thunderbolt) like the Sa'iqah which overtook 'Ad and Thamud (people)."

But if they turn away, say, “I have warned you of a thunderbolt, like the thunderbolt of Aad and Thamood.”
