Qur'an 2:271

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

“If you disclose your charitable expenditures, they are good; but if you conceal them and give them to the poor, it is better for you, and He will remove from you some of your misdeeds [thereby]. And Allāh, of what you do, is [fully] Aware.”
