Abu Sa'id Al-Khudri (RAA) narrated, “We used to offer it (Zakat-ul-fitr) during the lifetime of the Prophet (ﷺ) as one sa’ of food or one sa' of dates, or one sa' of barley or one sa' of raisins’’ Agreed upon. In another narration, “or one sa' of dried cottage cheese.” Abu Sa'id then added, “As for myself, I would continue to give it as I used to give during the time of the Prophet. Abu Dawud also transmitted on the authority of Abu Sa'id, “I would never give but a sa'.”

وَعَنْ أَبِي سَعِيدٍ اَلْخُدْرِيِّ ‏- رضى الله عنه ‏- قَالَ: { كُنَّا نُعْطِيهَا فِي زَمَانِ اَلنَّبِيِّ ‏- صلى الله عليه وسلم ‏-صَاعًا مِنْ طَعَامٍ, أَوْ صَاعًا مِنْ تَمْرٍ, أَوْ صَاعًا مِنْ شَعِيرٍ, أَوْ صَاعًا مِنْ زَبِيبٍ.‏ } مُتَّفَقٌ عَلَيْه ِ [1]‏ وَفِي رِوَايَةٍ: { أَوْ صَاعًا مِنْ أَقِطٍ } [2]‏ .‏ قَالَ أَبُو سَعِيدٍ: أَمَّا أَنَا فَلَا أَزَالُ أُخْرِجُهُ كَمَا كُنْتُ أُخْرِجُهُ فِي زَمَنِ رَسُولِ اَللَّهِ [3]‏ [4]‏ .‏ وَلِأَبِي دَاوُدَ: { لَا أُخْرِجُ أَبَدًا إِلَّا صَاعًا } [5]‏ .‏
