Grazing livestock: that which grazes for the entire year or most of it, and in which zakah is obligatory

Question : Now, suppose, for example, that she fasts for four months of the year, four months of the year she fasts, and for eight months of the year she is tethered. Is there zakah on her or not?

Answer : Yes, there is no zakah on her, because she is not grazing for the entire lunar year. Now, if she grazes for eight months and is tethered for four months, there is zakah on her, because she was grazing for most of the lunar year. And if she grazes for most of the lunar year, zakah becomes due on her. So, grazing livestock is that which grazes by itself for the lunar year or most of it. If it is tethered for the lunar year or most of it, or for half of the lunar year, it is not grazing livestock, so zakah is not obligatory on it.
