‘Ali reported the Prophet as saying,
“There is no sadaqa on green herbs, palm-trees given in usufruct for a year, less than five camel-loads, working animals, or al-jabha.” As-Saqr said al-jabha* consists of horses, mules and slaves.
Daraqutni transmitted it.
* Applied usually to horses, meaning the best type.
Ibn ‘Umar said God’s messenger prescribed as the zakat payable by slave and freeman, male and female, young and old among the Muslims on breaking the fast of Ramadan a sa'* of dried dates or a sa' of barley, and gave command that this should be paid before the people went out to prayer.
(Bukhari and Muslim.)
* The Hijazi sa' is described as a measure equivalent to four mudds, the mudd being the amount a man with average size hands can hold with both hands extended.
Rabi'a b. ‘Abd ar-Rahman on more than one person’s authority said,
“God’s messenger assigned as a fief to Bilal b. al-Harith al-Muzani the mines of al-Qabaliya which is in the neighbourhood of al-Fur‘,* and only zakat is levied on those mines up to the present day.”
Abu Dawud transmitted it.
* Yaqut, Mu'jam, ii, 471, says it is a village in the neighbourhood of ar-Rabadha, eight stages from Medina on the way to Mecca; some say four days’ journey.
