Surah Al-Ahzab — Ayah 66 (33:66)
يَوۡمَ تُقَلَّبُ وُجُوهُهُمۡ فِي ٱلنَّارِ يَقُولُونَ يَٰلَيۡتَنَآ أَطَعۡنَا ٱللَّهَ وَأَطَعۡنَا ٱلرَّسُولَا۠ ٦٦
English translation (Saheeh International)
The Day their faces will be turned about in the Fire, they will say, "How we wish we had obeyed Allāh and obeyed the Messenger."
Brief commentary
On the Day of Judgement their faces will be turned in the hellfire, and they will say out of severe regret and remorse: “If only we obeyed Allah by doing what He commanded us to and refrained from the things He prohibited us from, and obeyed the Messenger in what he brought from his Lord!”
