Sunan an-Nasa'i, Hadith 2508 ⓘ

When he was the governor of Al-Basrah, at the end of the month, Ibn 'Abbas said: "Give Zakah of your fast." The people looked at one another, so he said: "Whoever is here from the people of Al-Madinah, get up and teach your brothers, for they do lnot know that this Zakah was enjoined by the Messenger of Allah upon every male and female, free and slave, a Sa' of barley or dates, or half a Sa' of wheat. "So they got up. (Da'if) Hisham contradicted him, he said: "From Muhammad bin Sirin."
