Aishah said: The Messenger of Allah صلی اللہ علیہ وسلم used to take bath with from a vessel (which contained seven to eight seers, i. e., fifteen to sixteen pounds) because of sexual intercourse. Abu Dawud said: The version narrated by Mu’ammar on the authority of al-Zuhri has: She (Aishah) said: I and the Messenger of Allah صلی اللہ علیہ وسلم took a bath from a vessel which was equal to al-faraq in measurement (i. e., containing water about seven or eight seers). Abu Dawud said: Ibn ‘Uyainah also narrated like the version of Malik. Abu Dawud said; I heard Ahmad bin Hanbal say: Al-Faraq contains sixteen rotls (of water). I also heard him say: The sa’of of Ibn Abi Dhi’b contained 5 rotls (of water). The view that a sa’ contains eight rotls (of water) is not safe. Abu Dawud said: I heard Ahmad (b. Hanbal) say: Whoever gave 5 1/3 rotls (measuring) with our rotl alms of fitr (sadaqat al-fitr), he gave in full, Thereupon he was questioned: Are the dates called al-saihani heavier (can one sa’ of them be given as alms of fitr)? He replied: The dates called al-saihani are good. But I do not know (whether water is heavier or the dates).
