Al-Ahzab 33:19
أَشِحَّةً عَلَيْكُمْ ۖ فَإِذَا جَآءَ ٱلْخَوْفُ رَأَيْتَهُمْ يَنظُرُونَ إِلَيْكَ تَدُورُ أَعْيُنُهُمْ كَٱلَّذِى يُغْشَىٰ عَلَيْهِ مِنَ ٱلْمَوْتِ ۖ فَإِذَا ذَهَبَ ٱلْخَوْفُ سَلَقُوكُم بِأَلْسِنَةٍ حِدَادٍ أَشِحَّةً عَلَى ٱلْخَيْرِ ۚ أُو۟لَـٰٓئِكَ لَمْ يُؤْمِنُوا۟ فَأَحْبَطَ ٱللَّهُ أَعْمَـٰلَهُمْ ۚ وَكَانَ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرًا

Indisposed toward you. And when fear comes, you see them looking at you, their eyes revolving like one being overcome by death. But when fear departs, they lash you with sharp tongues, indisposed toward [any] good. Those have not believed, so Allāh has rendered their deeds worthless, and ever is that, for Allāh, easy.
(and that too) with a greed against you (i.e. to extract a share of spoils from you). But when fear comes, you will see them looking towards you, rolling their eyes, like the one who gets faint because of death. Then once fear is gone, they assail you with sharp tongues, in greed for the good (i.e. the wealth acquired as spoils). These people did not accept faith (in real terms), therefore Allah has nullified their acts. All this is so easy for Allah.
