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 ۚ أُو۟لَٰٓئِكَ لَمْ يُؤْمِنُوا۟ فَأَحْبَطَ ٱللَّهُ أَعْمَٰلَهُمْ ۚ وَكَانَ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرًۭا ﴿19﴾

Being sparing of their help to you (believers). But when the fear cometh, then thou (Muhammad) seest them regarding thee with rolling eyes like one who fainteth unto death. Then, when the fear departeth, they scald you with sharp tongues in their greed for wealth (from the spoil). Such have not believed. Therefor Allah maketh their deeds fruitless. And that is easy for Allah.
