Mishkat al-Masabih 1940 — Zakat

Abu Hurairah Narrated from:

When a man came to the Prophet saying that he had a dinar, he told him to spend it on himself. He said that he had another, and he told him to spend it on his children. He said that he had another, and he told him to spend it on his wife. He said that he had another, and he told him to spend it on his servant. He said he had another and he replied, “You know best [what to do with it]." Abu Dawud and Nasa’i transmitted it.
