The Prophet ﷺ said, "The best charity is that given out of surplus wealth, and begin with those you support."
عن النبي ﷺ قال: خير الصدقة ما كان عن ظهر غنى، وابدأ بمن تعول.
Bukhari narrated it in the chapter on zakat (1426), from Abdan, who said, Abdullah bin Yunus informed us, from Zuhri, who said, Saeed bin Musayab informed me that he heard Abu Hurairah, and then he related the hadith.His saying, "from a position of sufficiency," means from what suffices him and those he supports.
