Sa’ad ibn Abdullah from Ahmad ibn Muhammad from Abd al-Rahman ibn Abi Najran from Asim ibn Humayd, and al-Husayn ibn Said from al-Nadr ibn Suwayd from Asim ibn Humayd from Abu Basir from Abu Abdillah: I (narrator) asked Imam Ja’far al-Sadiq (a.s) about ‘zakat.’ Imam (a.s) said: “There is nothing due on fewer than five camels. When they reach five camels, one sheep is due on them, up to ten camels. When they reach ten camels, two sheep are due on them, up to fifteen camels. When they reach fifteen camels, three sheep are due on them, up to twenty camels. When they reach twenty, four sheep are due on them, up to twenty-five camels. When they reach twenty-five camels, five sheep are due on them. Then, if they increase by one, a she-camel in its second year (ibnat makhad) is due on them, up to thirty-five camels. If there is no she-camel in its second year, then a male camel in its third year (ibn labun) is due. Then, if they increase by one beyond thirty-five, a female camel in its third year (bint labun) is due on them, up to forty-five camels. Then, if they increase by one beyond forty-five, a she-camel in its fourth year (hiqqah) is due on them, up to sixty camels. Then, if they increase by one beyond sixty, a she-camel in its fifth year (jadhah) is due on them, up to seventy-five camels. Then, if they increase by one beyond seventy-five, two female camels in their third year (binta labun) are due on them, up to ninety camels. Then, if they increase by one beyond ninety, two she-camels in their fourth year (hiqqatan) are due on them, up to one hundred and twenty camels. Then, when the camels become numerous, then for every fifty camels, one she-camel in its fourth year (hiqqah) is due. An old animal is not to be taken for zakat, nor an animal with a defect, unless the collector of charity wishes to count both its young and its old.”
