﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تُبْطِلُوا۟ صَدَقَٰتِكُم بِٱلْمَنِّ وَٱلْأَذَىٰ كَٱلَّذِى يُنفِقُ مَالَهُۥ رِئَآءَ ٱلنَّاسِ وَلَا يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ ۖ فَمَثَلُهُۥ كَمَثَلِ صَفْوَانٍ عَلَيْهِ تُرَابٌۭ فَأَصَابَهُۥ وَابِلٌۭ فَتَرَكَهُۥ صَلْدًۭا ۖ لَّا يَقْدِرُونَ عَلَىٰ شَىْءٍۢ مِّمَّا كَسَبُوا۟ ۗ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلْكَٰفِرِينَ ﴾

“O you who have attained to faith! Do not deprive your charitable deeds of all worth by stressing your own benevolence and hurting [the feelings of the needy], as does he who spends his wealth only to be seen and praised by men, and believes not in God and the Last Day: for his parable is that of a smooth rock with [a little] earth upon it - and then a rainstorm smites it and leaves it hard and bare. Such as these shall have no gain whatever from all their [good] works: for God does not guide people who refuse to acknowledge the truth.”

O you who believe annul not the rewards of your voluntary almsgivings with reproach and injury as in the manner of the annulment of the expenditure of one who expends of his substance to show off to men and believes not in God and the Last Day this is the hypocrite. The likeness of him is as the likeness of a smooth rock on which is soil and a torrent of intense rain smites it and leaves it barren and smooth with nothing on it. They have no power lā yaqdirūna is a resumption of the statement about the likeness of the one that expends for show; the person becomes plural on account of the potential plural implication of alladhī ‘the one who’ over anything that they have earned that they did in other words they find no reward for it in the Hereafter just as one finds nothing of the dust that was on the surface of the smooth rock after the rain has washed it away. God guides not the disbelieving folk.
