Al-Muwatta Hadith 17.23

Yahya related to me from Malik that he had read what Umar ibn al-Khattab had written about zakat, and in it he found: "In the name of Allah, the Merciful, the ompassionate." The Book of Zakat. On twenty-four camels or less zakat is paid with sheep, one ewe for every five camels. On anything above that, up to thirty-five camels, a she-camel in its second year, and, if there is no she camel in its second year, a male camel in its third year. On anything above that, up to forty-five camels, a she-camel in its third year. On anything above that, up to sixty camels, a she camel in its fourth year that is ready to be sired. On anything above that, up to seventy-five camels, a she-camel in its fifth year. On anything above that, up to ninety camels, two she-camels in their third year. On anything above that, up to one hundred and twenty camels, two she-camels in their fourth year that are ready to be sired. On any number of camels above that, for every forty camels, a she-camel in its third year, and for every fifty, a she-camel in its fourth year. On grazing sheep and goats, if they come to forty or more, up to one hundred and twenty head, one ewe. On anything above that, up to two hundred head, two ewes. On anything above that, up to three hundred, three ewes. On anything above that, for every hundred, one ewe. A ram should not be taken for zakat. nor an old or an injured ewe, except as the zakat-collector thinks fit. Those separated should not be gathered together nor should those gathered together be separated in order to avoid paying zakat. Whatever belongs to two associates is settled between them proportionately. On silver, if it reaches five awaq (two hundred dirhams), one fortieth is paid."
