﴿ 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.”

grudging to you in their help ashihha ‘grudging’ is the plural of shahīh and is a circumstantial qualifier referring to the subject of the verb ya’tūna ‘they engage’. And when there is a panic you see them looking at you their eyes rolling like one that is like the look of one or the rolling of one fainting at death in other words one in the throes thereof; but when the panic subsides and the spoils have been secured they scald you they hurt you or they smite you with their sharp tongues in their greed for the riches in other words for the spoils which they demand greedily. Those they never believed really. Therefore God has invalidated their works and that invalidation is easy for God by His will.
