Quran 2:271 Al-Baqarah, ayah 271 of 286

إِن تُبْدُوا۟ ٱلصَّدَقَـٰتِ فَنِعِمَّا هِىَ ۖ وَإِن تُخْفُوهَا وَتُؤْتُوهَا ٱلْفُقَرَآءَ فَهُوَ خَيْرٌ لَّكُمْ ۚ وَيُكَفِّرُ عَنكُم مِّن سَيِّـَٔاتِكُمْ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ ۝٢٧١

2:271 If ye publish your almsgiving, it is well, but if ye hide it and give it to the poor, it will be better for you, and will atone for some of your ill-deeds. Allah is Informed of what ye do.
