BAYHAQI 7703:
from Ibn ʿUmar —
[Machine] The Messenger of Allah ﷺ prescribed the Zakat al-Fitr, which is a Sa'a of dates or a Sa'a of barley, upon every free man or slave, male or female, among the Muslims. This was narrated by Sa'id bin 'Abdul Rahman al-Jumahi, and the mention of barley in it is not preserved.
البيهقي ٧٧٠٣:
عن ابن عمر —
أَنَّ رَسُولَ اللهِ ﷺ فَرَضَ زَكَاةَ الْفِطْرِ صَاعًا مِنْ تَمْرٍ أَوْ صَاعًا مِنْ بُرٍّ عَلَى كُلِّ حُرٍّ أَوْ عَبْدٍ ذَكَرٍ أَوْ أُنْثَى مِنَ الْمُسْلِمِينَ كَذَا قَالَهُ سَعِيدُ بْنُ عَبْدِ الرَّحْمَنِ الْجُمَحِيُّ وَذِكْرُ الْبُرِّ فِيهِ لَيْسَ بِمَحْفُوظٍ
