12. When spend in Allah's cause do not show to others (Zakat and Zakatul Fitr)

Surah No. 2, Al Baqr, Ayat No. 264

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تُبْطِلُوا صَدَقَاتِكُمْ بِالْمَنِّ وَالْأَذَىٰ كَالَّذِي يُنْفِقُ مَالَهُ

رِئَاءَ النَّاسِ وَلَا يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَمَثَلُهُ كَمَثَلِ صَفْوَانٍ عَلَيْهِ تُرَابٌ

فَأَصَابَهُ وَابِلٌ فَتَرَكَهُ صَلْدًا لَا يَقْدِرُونَ عَلَىٰ شَيْءٍ مِمَّا كَسَبُوا وَاللَّهُ لَا

o يَهْدِي الْقَوْمَ الْكَافِرِينَ

Translation :

O believers! do not destroy your charity by giving reminders of your generosity and hurting the acceptors.― like those who spend their wealth to be seen by other men, but they believe neither in Allah nor in the Last Day. Their example is like a hard, barren rock, on which there is a little soil; when heavy rain falls on it, which exposes a bare stone. They will be able to do nothing with what they have earned. And Allah does not guide those who reject faith.

Surah No. 4, An Nisa, Ayat No. 38

وَالَّذِينَ يُنفِقُونَ أَمْوَالَهُمْ رِئَـاء النَّاسِ وَلاَ يُؤْمِنُونَ بِاللّهِ وَلاَ بِالْيَوْمِ الآخِرِ وَمَن يَكُنِ

o الشَّيْطَانُ لَهُ قَرِينًا فَسَاء قِرِينًا

Translation :

And those who spend their wealth to be seen by other men, and they do not believe in Allah and the Last Day, then shaitan becomes their companion, just think what a bad companion he is?
