Heedlessness of Disbelievers

نُسَارِعُ لَهُمْ فِى ٱلْخَيْرَٰتِ ۚ بَل لَّا يَشْعُرُونَ

Is [because] We hasten for them good things? Rather, they do not perceive.

مَا يَنظُرُونَ إِلَّا صَيْحَةً وَٰحِدَةً تَأْخُذُهُمْ وَهُمْ يَخِصِّمُونَ

They do not await except one blast which will seize them while they are disputing.
