﴿ فَلَمَّآ ءَاسَفُونَا ٱنتَقَمْنَا مِنْهُمْ فَأَغْرَقْنَٰهُمْ أَجْمَعِينَ ﴾

“But when they continued to challenge Us, We inflicted Our retribution on them, and drowned them all:”

(So, when they angered Us) when they angered Our Prophet Moses, and tended to anger Us, (We punished them and drowned them every one) in the sea.
