the two qullahs are five qirbas, which is five hundred ratls. Sa'id narrated, saying: 'Abd al-'Aziz ibn Muhammad narrated to us, 'Abd al-Rahman ibn al-Harith ibn Abi Dhubab informed me, from his father, from his grandfather, that he said to his people: "There is no good in wealth that has no Zakah on it." He said: So I took one qirba from every ten qirbas, and I brought it to 'Umar ibn al-Khattab, and he took it and placed it into the charities of the Muslims. The rationale for the first [view] is the statement of 'Umar: "From every ten faraqs, there is one faraq." The faraq, with the vowel on the ra', is sixteen ratls. Abu 'Ubayd said: I know of no disagreement among the people that the faraq is three sa's. The Prophet (peace and blessings of Allah be upon him) said to Ka'b ibn 'Ujrah: "Feed six poor persons a faraq of food." Thus, he clarified that it is three sa's. 'A'ishah said: "I and the Messenger of Allah (peace and blessings of Allah be upon him) used to perform ghusl from one vessel, which was the faraq." This is the well-known [definition], so the absolute term is referred to it. As for the farq—being a large vessel—it is not valid to apply it to this for several reasons: First, it is not well-known in their speech, so their absolute statements are not interpreted based on it. Tha'lab said: Say "faraq" and do not say "farq". Khidash ibn Zuhayr said:

They take the blood money (arsh) from their brothers... A faraq of clarified butter and a sheep among the flock.

Second, 'Umar said: "From every ten faraqs, one faraq." The term "afraq" is the plural of "faraq" with a fatha on the ra', while the plural of "farq" with a sukun on the ra' is "furuq", and in small numbers it is "afruq"; for whatever is on the measure of "fa'l" with a vowelled second letter and is not defective, its plural in small numbers is "af'ul", and in large numbers it is "fi'al" or "fu'ul".
