Sunan an-Nasa'i 2518
أَخْبَرَنَا عِيسَى بْنُ حَمَّادٍ، قَالَ أَنْبَأَنَا اللَّيْثُ، عَنْ يَزِيدَ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُثْمَانَ، أَنَّ عِيَاضَ بْنَ عَبْدِ اللَّهِ بْنِ سَعْدٍ، حَدَّثَهُ أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ قَالَ كُنَّا نُخْرِجُ فِي عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم صَاعًا مِنْ تَمْرٍ أَوْ صَاعًا مِنْ شَعِيرٍ أَوْ صَاعًا مِنْ أَقِطٍ لاَ نُخْرِجُ غَيْرَهُ .
Isa ibn Hammad reported: al-Layth informed us, from Yazid, from Ubayd Allah ibn Abd Allah ibn Uthman, that Iyad ibn Abd Allah ibn Sad related to him that Abu Saeed al-Khudri said: In the time of the Messenger of Allah ﷺ, we used to give one sa of dates, or one sa of barley, or one sa of aqit; we did not give anything else.
Translation notes
The source explicitly limits the listed practice to these three foods and says no other food was given. Aqit is a dried curd product.
