Ayoub al-Sakhtiyani أيوب السختياني · The Book of Zakah

"The injuries caused by the beast are without liability, and wells are without liability, and mines are without liability, and the Khumus is due on Rikaz."

A similar report was narrated from Abu Hurairah from the Messenger of Allah.

"The Messenger of Allah enjoined Sadaqatul Fitr upon young and old, male and female, free and slave; a Sa' of dates or a Sa' of barley,"

" The poor man stands at my door, and I cannot find anything to give him. " The Messenger of Allah said to her: "If you cannot find anything to give to him except a sheep's burned foot, then give it to him."
