إِنْ تُبْدُوا الصَّدَقَاتِ فَنِعِمَّا هِيَ ۖ وَإِنْ تُخْفُوهَا وَتُؤْتُوهَا الْفُقَرَاءَ فَهُوَ خَيْرٌ لَكُمْ ۚ وَيُكَفِّرُ عَنْكُمْ مِنْ سَيِّئَاتِكُمْ ۗ وَاللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ 271
If ye disclose (acts of) charity, even so it is well, but if ye conceal them, and make them reach those (really) in need, that is best for you: It will remove from you some of your (stains of) evil. And Allah is well acquainted with what ye do.
