يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تُبْطِلُوا۟ صَدَقَـٰتِكُم بِٱلْمَنِّ وَٱلْأَذَىٰ كَٱلَّذِى يُنفِقُ مَالَهُۥ رِئَآءَ ٱلنَّاسِ وَلَا يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ ۖ فَمَثَلُهُۥ كَمَثَلِ صَفْوَانٍ عَلَيْهِ تُرَابٌ فَأَصَابَهُۥ وَابِلٌ فَتَرَكَهُۥ صَلْدًا ۖ لَّا يَقْدِرُونَ عَلَىٰ شَىْءٍ مِّمَّا كَسَبُوا۟ ۗ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلْكَـٰفِرِينَ

O you who have believed, do not invalidate your charities with reminders [of it] or injury as does one who spends his wealth [only] to be seen by the people and does not believe in Allāh and the Last Day. His example is like that of a [large] smooth stone upon which is dust and is hit by a downpour that leaves it bare. They are unable [to keep] anything of what they have earned. And Allāh does not guide the disbelieving people.

Al-Baqarah 264
