﴿ إِن تُبْدُوا۟ ٱلصَّدَقَٰتِ فَنِعِمَّا هِىَ ۖ وَإِن تُخْفُوهَا وَتُؤْتُوهَا ٱلْفُقَرَآءَ فَهُوَ خَيْرٌۭ لَّكُمْ ۚ وَيُكَفِّرُ عَنكُم مِّن سَيِّـَٔاتِكُمْ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌۭ ﴾

“If you do deeds of charity openly, it is well; but if you bestow it upon the needy in secret, it will be even better for you, and it will atone for some of your bad deeds. And God is aware of all that you do.”

[If you proclaim your voluntary almsgivings, it is a fine thing; but if you conceal them, and give them to the poor] that is even better for you: because of this being far removed from making a show and closer to sincerity [of intention].
