Musannaf Ibn Abi Shaybah

Hazrat Sa’d bin Abu Dhibab came to his people and said to them: “There is zakat in honey, and there is no good in that wealth from which zakat is not paid.” The narrator says that the people asked, “How much is it?” He replied, “A tenth.” Then he collected a tenth from them and took it to Hazrat Umar and informed him about it. Hazrat Umar took the collected tenth from him and placed it with the zakat (collected from the Muslims).
