The meaning of the ages of camels which are taken in alms tax

1. We were told by my father, may Allah be pleased with him, that he said: We were told by Sa’d bin Abdullah, from Ibrahim bin Hashim, from Hammad bin Isa, from Huraiz, from Zurara, and Muhammed bin Muslim, and Abu Baseer, and Buraid al-‘Ajali, and Fudail, from Abu Ja’far and Abu Abdillah, peace be upon them both, that they both said with regards to the charity for camels: It is for every five sheep until they reach twenty-five, and if they reach that, for for that is a child at birth. Then, there is nothing in that until they reach thirty-five, and if they reach thirty-five, for that is one that is milked. Then, there is nothing in that until they reach forty-five, and if they reach forty-five, for that is a three-year-old female camel that can be approached by a male. Then, there is nothing in that until they reach sixty, and if they reach sixty, for that is a four-year-old female camel. Then, there is nothing for that until they reach seventy-five, and if they reach seventy-five, for that are two that are milked. Then, there is nothing for that until they reach ninety, and if they reach ninety, for that are two three-year-old female camels that can be approached by a male. Then, there is nothing for that until they reach a hundred and twenty, and if they reach a hundred and twenty, for that are two three-year-old camels that can be approached by a male. Then, if one is added onto a hundred and twenty, for every fifty there is one three-year-old female camel, and for every forty, there is one that is milked. Then, the camels are to be calculated again by their ages. There is nothing for nayyif, nor for kusour, and there is nothing for ‘awamil. That is only for the freely eating that are herded. He said
