Al Baqarah Ayah 271

إِن تُبْدُواْ ٱلصَّدَقَـٰتِ فَنِعِمَّا هِىَ‌ۖ وَإِن تُخْفُوهَا وَتُؤْتُوهَا ٱلْفُقَرَآءَ فَهُوَ خَيْرٌ لَّكُمْ‌ۚ وَيُكَفِّرُ عَنكُم مِّن سَيِّـَٔـاتِكُمْ‌ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ ٢٧١ To give charity publicly is good, but to give to the poor privately is better for you, and will absolve you of your sins. And Allah is All-Aware of what you do.
