Qutayba bin Sa'id bin Jamil قتيبة بن سعيد بن جميل · The Book on Zakat

the Prophet said: "There is no charity due on less than five camels, and there is no charity due on what is less than five Uqiyah (of silver), and there is no charity due on what is less than five Wasaq."

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 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."

the Messenger of Allah said: "Whoever begs from the people while he has what he needs, he will come on the Day of Judgment and his begging with be scratches or lacerations, or bite marks on his face." They said: "O Messenger of Allah! 'How much is it that one needs?' He said: 'Fifty Dirham, or their value in gold.'"

"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 Prophet said: "When one of you breaks his fast, then let him do so with dried dates, for they are blessed. Whoever does not find dates, then water, for it is purifying." And he said: "Charity given to the needy is (counted as) charity, and if it is given to relatives it is (counted as) two: charity and nurturing (the ties of kinship)."

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."

"The Messenger of Allah made Sadaqatul-Fitr an obligation upon the male and female, the free and the bondsmen, as a Sa of dried dates or a Sa of barley." He said: "So the people equated that to half a Sa of wheat."
