Surah Al-A'raf — Ayah 136 (7:136)
فَٱنتَقَمۡنَا مِنۡهُمۡ فَأَغۡرَقۡنَٰهُمۡ فِي ٱلۡيَمِّ بِأَنَّهُمۡ كَذَّبُواْ بِـَٔايَٰتِنَا وَكَانُواْ عَنۡهَا غَٰفِلِينَ ١٣٦
English translation (Saheeh International)
So We took retribution from them, and We drowned them in the sea because they denied Our signs and were heedless of them.
Brief commentary
So when the appointed time came for their destruction, I unleashed My punishment on them and drowned them in the sea because of their rejection of the signs of Allah and because they turned away from the truth about which there was no doubt.
