Al Baqarah Ayah 264

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تُبْطِلُواْ صَدَقَـٰتِكُم بِٱلْمَنِّ وَٱلْأَذَىٰ كَٱلَّذِى يُنفِقُ مَالَهُۥ رِئَآءَ ٱلنَّاسِ وَلَا يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْأَخِرِ‌ۖ فَمَثَلُهُۥ كَمَثَلِ صَفْوَانٍ عَلَيْهِ تُرَابٌ فَأَصَابَهُۥ وَابِلٌ فَتَرَكَهُۥ صَلْدًا‌ۖ لَّا يَقْدِرُونَ عَلَىٰ شَىْءٍ مِّمَّا كَسَبُواْ‌ۗ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلْكَـٰفِرِينَ ٢٦٤ O believers! Do not waste your charity with reminders ?of your generosity? or hurtful words, like those who donate their wealth just to show off and do not believe in Allah or the Last Day. Their example is that of a hard barren rock covered with a thin layer of soil hit by a strong rain—leaving it just a bare stone. Such people are unable to preserve the reward of their charity. Allah does not guide ?such? disbelieving people.
