Al-A'raf - 7:136

فَانتَقَمْنَا مِنْهُمْ فَأَغْرَقْنَاهُمْ فِي الْيَمِّ بِأَنَّهُمْ كَذَّبُواْ بِآيَاتِنَا وَكَانُواْ عَنْهَا غَافِلِينَ
[7:136]
Therefore We inflicted retribution on them and drowned them in the sea because they rejected Our signs and were heedless of them.
So We exacted retribution from them: We drowned them in the sea, because they rejected Our Signs and failed to take warning from them.
Therefore We took retribution from them; therefore We drowned them in the sea: because they denied Our revelations and were heedless of them.
