﴿ 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 ﴾

“begrudging you all help. But then, when danger threatens, thou canst see them looking to thee [for help, O Prophet], their eyes rolling [in terror] like [the eyes of] one who is overshadowed by death: yet as soon as the danger has passed, they will assail you [believers] with sharp tongues, begrudging you all that is good! [People like] these have never known faith - and therefore God will cause all their works to come to nought: for this is indeed easy for God.”

There are those who lag behind at the time when sacrifice is required, but who feel ashamed of this shortcoming. Then there are others who do not make sacrifices when they are called for, but who feel no shame on this account. This amounts to adding arrogance to neglect of duty. A shortcoming may be pardonable, but arrogance is not. Even if some apparently good deeds are performed by those who are flawed by arrogance, they are worthless, because the essence of a good deed is sincerity, and that is the very thing which is lacking. Shirking the duty of making sacrifices for a religious cause is invariably the result of a love for worldly affairs. Man loses his faith for the sake of saving his worldly assets. When materially-minded people see that worldly advantage is coupled with religion, they display their oratorical skill in speaking in favour of religion, in order to show off their connection with religion and then they extract the maximum advantage from this. But when following religion means sacrifice, they lose interest in becoming men of religion. Wandering Arabs.
