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.
وَعَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ: كُنَّا نُخْرِجُ زَكَاةَ الْفِطْرِ صَاعًا مِنْ طَعَامٍ أَو صَاعا من شعير أَو صَاعا من تَمْرٍ أَوْ صَاعًا مَنْ أَقِطٍ أَوْ صَاعًا من زبيب
Abu Sa'id al-Khudrl said,
“We used to bring forth as the zakat on breaking the fast of Ramadan a sa’ of grain, or of barley, or of dried dates, or of cheese, or of raisins."
‘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.
