if you give charity openly that is good. but if you keep it secret and give it to the needy in private that is better for you. it will atone for some of your misdeeds. god is cognizant of what you do.
إن تبدوا الصدقات فنعما هي وإن تخفوها وتؤتوها الفقراء فهو خير لكم ويكفر عنكم من سيئاتكم والله بما تعملون خبير
