Sura al-Aḥzāb 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 ٱللَّـهُ أَعْمَٰلَهُمْ وَكَانَ ذَٰلِكَ عَلَى ٱللَّـهِ يَسِيرًا

asḥiḥḥatan ʿalaykum fa-idhā jāa l-khawfu raʾaytahum yanẓurūna ilayka tadūru aʿyunuhum ka-lladhī yughsha ʿalayhi mina l-mawti fa-idhā dhahaba l-khawfu salaqūkum bi-alsinatin ḥidādin asḥiḥḥatan ʿalā l-khayri ulāʾika lam yuʾminū fa-aḥbaṭa allāhu aʿmālahum wa-kāna dhālika ʿalā allāhi yasīran

Covetous over you. Then when fear comes, thou wilt see them looking to thee, their eyes revolving, like (those of) one over whom hovers death: but when the fear is past, they will smite you with sharp tongues, covetous of goods. Such men have no faith, and so Allah has made their deeds of none effect: and that is easy for Allah.
