‘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."
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.
‘Abdallah b. Tha'laba, or Tha'laba b. ‘Abdallah b. Abu Su'air* reported on his father’s authority that God’s messenger said,
“A sa’ of wheat** is to be taken from every two, young or old, freeman or slave, male or female. Those of you who are rich will be purified by God and those of you who are poor will have more than they gave returned by Him to them.”
Abu Dawud transmitted it.
* Abu Dawud, zakat, 21 gives the name as above, but others often give b. Su'air. Ibn 'Abd al-Barr in Isti'ab and Ibn Hajar in Tahdhib give b. Su'air, adding that b. Abu Su'air also occurs.
** The transmitter is not sure which word for "wheat” was used, so he gives either burr or qamh.
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."
