The obligation of Zakat on livestock is established by the Quran, the Sunnah, and scholarly consensus. The consensus has been reported by numerous scholars, among them Ibn al-Mundhir. This is also confirmed by the hadith of the Sadaqah letter which the Prophet ๏ทบ wrote and sent to his governors, detailing the Nisab amounts for Zakat on camels, cattle, and sheep.
Conditions for Zakat on Livestock to be Obligatory:
Islam
Freedom
Full Ownership
Reaching Nisab
Completion of One Lunar Year
Being Free-Grazing (Sa'imah)
Sa'imah: Livestock that depend on free grazing for most of the year for their sustenance. If they are stall-fed all year, no livestock Zakat applies; instead, they are zakated as trade goods if held for trading purposes.
