heedlessness and negligence

فَٱنتَقَمْنَا مِنْهُمْ فَأَغْرَقْنَـٰهُمْ فِى ٱلْيَمِّ بِأَنَّهُمْ كَذَّبُوا۟ بِـَٔايَـٰتِنَا وَكَانُوا۟ عَنْهَا غَـٰفِلِينَ

So We took retribution from them, and We drowned them in the sea because they denied Our signs and were heedless of them.

ٱلَّذِينَ هُمْ فِى غَمْرَةٍ سَاهُونَ

Who are within a flood [of confusion] and heedless.
