Quran 33, Al-Ahzab (Confederates) ⓘ

33:19Being 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.

أَشِحَّةً عَلَيْكُمْ فَإِذَا جَاءَ الْخَوْفُ رَأَيْتَهُمْ يَنْظُرُونَ إِلَيْكَ تَدُورُ أَعْيُنُهُمْ كَالَّذِي يُغْشَى عَلَيْهِ مِنَ الْمَوْتِ فَإِذَا ذَهَبَ الْخَوْفُ سَلَقُوكُمْ بِأَلْسِنَةٍ حِدَادٍ أَشِحَّةً عَلَى الْخَيْرِ أُولَئِكَ لَمْ يُؤْمِنُوا فَأَحْبَطَ اللَّهُ أَعْمَالَهُمْ وَكَانَ ذَلِكَ عَلَى اللَّهِ يَسِيرًا
