al-Laith bin Sa'd الليث بن سعد · The Book on Zakat

the Messenger of Allah said: "The injuries caused by the animal are without liability, and mines are without liability, and wells are without liability, and the Khumus is due on Rikaz."

the Messenger of Allah said: "The one who commits transgression with charity is like the one who does not pay it."

"During the time of the Messenger of Allah, a man suffered a loss on fruits that he had sold, resulting in more debt. The Messenger of Allah said: 'Give him charity.' So the people gave him charity but it did not cover his debt. So the Messenger of Allah said to his debtors: 'Take what you have and there is nothing for you but that.'"

the Messenger of Allah said: "None gives charity from Tayyib - and Allah does not accept but Tayyib - but that Ar-Rahman accepts it with His Right (Hand). Even if it is a date, it is nurtured in the Hand of Ar-Rahman until it is greater than a mountain, just as one of you nurtures his foal or young camel."

Umm Bujaid - and she was one of those who gave the pledge to the Prophet - she said to the Messenger of Allah: "There is a needy person who stands outside my door, but I cannot find anything to give to him." So the Messenger of Allah said to her: "If you do not find anything to give him except a burnt trotter then hand it over to him."
