The Book of Zakah
وَلَهُ مِنْ حَدِيثِ أَبِي سَعِيدٍ: { لَيْسَ فِيمَا دُونَ خَمْسَةِ أَوْسَاقٍ مِنْ تَمْرٍ وَلَا حَبٍّ صَدَقَةٌ } [1] . وَأَصْلُ حَدِيثِ أَبِي سَعِيدٍ مُتَّفَقٌ عَلَيْه ِ [2] .
Abu Said Al-Khudri (RAA) narrated that The Messenger of Allah (ﷺ) said: “There is no Zakah to be paid on any amount of dates or grain less than five Awsuq.” Agreed upon.
