Al-Baqarah 2:264
يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تُبْطِلُوا صَدَقَاتِكُم بِالْمَنِّ وَالْأَذَىٰ كَالَّذِي يُنفِقُ مَالَهُ رِئَاءَ النَّاسِ وَلَا يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ ۖ فَمَثَلُهُ كَمَثَلِ صَفْوَانٍ عَلَيْهِ تُرَابٌ فَأَصَابَهُ وَابِلٌ فَتَرَكَهُ صَلْدًا ۖ لَّا يَقْدِرُونَ عَلَىٰ شَيْءٍ مِّمَّا كَسَبُوا ۗ وَاللَّهُ لَا يَهْدِي الْقَوْمَ الْكَافِرِينَ ٢٦٤

O believers, void not your freewill offerings with reproach and injury, as one who expends of his substance to show off to men and believes not in God and the Last Day. The likeness of him is as the likeness of a smooth rock on which is soil, and a torrent smites it, and leaves it barren. They have no power over anything that they have earned. God guides not the people of the unbelievers. (2:264)
