Shu'aib bin Muhammad bin 'Abdullah شعيب بن محمد بن عبد الله بن عمرو · The Book on Zakat

that two women came to the Messenger of Allah, and they each had a bracelet of gold on their forearms. So he said to them: "Have you paid their Zakat?" They said, "No." The Messenger of Allah said to them: "Would you like for Allah to fashion then into two bracelets of Fire?" They said, "No." He said: "Then pay its Zakat."

the Prophet addressed the people and said: "As for one who is the guardian of an orphan who has wealth, then let him do business with it and not leave it until it becomes consumed by charity."

the Prophet sent a caller in the roads of Makkah proclaiming "Sadaqatul-Fitr is required upon every Muslim, male or female, free or slave, young or old; it is two Mudd of wheat or its equivalent of a Sa of food."
