Ali ibn al-Hasan ibn Faddal from Muhammad and Ahmad, the two sons of al-Hasan, from their father, from al-Qasim ibn Urwah, from Abdullah ibn Bukayr, from Zurarah, from Abu Ja’far عليه السلام and Abu Abdillah عليه السلام, peace be upon them both, said: Imam عليه السلام said: “There is nothing due on camels until they reach five. When they reach five, one sheep is due on them. Then, for every five camels, one sheep is due, until they reach twenty-five. Then, if they increase by one, a she-camel in its second year (ibnat makhad) is due on them. If there is no she-camel in its second year (ibnat makhad) among them, then a male camel in its third year (ibn labun) is due, up to thirty-five. Then, if they increase beyond thirty-five, a female camel in its third year (ibnat labun) is due, up to forty-five. Then, if they increase, a she-camel in its fourth year (hiqqah) is due, up to sixty. Then, if they increase, a she-camel in its fifth year (jadhah) is due, up to seventy-five. Then, if they increase, two female camels in their third year (binta labun) are due, up to ninety. Then, if they increase, two she-camels in their fourth year (hiqqatan) are due, up to one hundred and twenty. Then, if they increase beyond that, then for every fifty camels, one she-camel in its fourth year (hiqqah) is due, and for every forty camels, one female camel in its third year (ibnat labun) is due. There is no zakat on any animals other than these categories which we have named. And whatever belongs to these categories but is kept domestically (al-dawajin) or used as working animals (al-awamil), there is nothing due on them. And as for these three categories, camels, cattle, and sheep, nothing is due on them until a full year has passed over them from the day they were born.”
