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