He said that God’s messenger prescribed the zakat relating to the breaking of the fast as a purification of the fasting from empty and obscene talk and as food for the poor.
Ibn 'Abbas said,
“At the end of Ramadan bring forth the sadaqa relating to your fast. God's messenger prescribed this sadaqa as a sa' of dried dates or barley, or half a sa' of wheat payable by every free¬man or slave, male or female, young or old."
‘Amr b. Shu'aib on his father’s authority said his grandfather told that the Prophet sent someone to announce in the ravines of Mecca,
“The sadaqa relating to the breaking of the fast is incumbent on every Muslim, male or female, freeman or slave, young or old, consisting of two mudds of wheat or such like, or a sa' of grain."
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."
